The chlorine trifluoride chemical formula is ClF3. Drawing ClF3 Lewis Structure is very easy to by using the following method. Here in this post, we described step by step method to construct ClF3 Lewis Structure. The chlorine and fluorine elements come as the member of the halogen family group from the periodic table. The valence electrons in chlorine and fluorine are seven. The branch of halogen chemistry is used to make chemicals reagents for fluorination reactions.
Key Points To Consider When Drawing The ClF3 Electron Dot Structure
A three-step approach for drawing the ClF3 Lewis structure can be used. The first step is to sketch the Lewis structure of the ClF3 molecule, to add valence electrons around the chlorine atom; the second step is to add valence electrons to the three fluorine atoms, and the final step is to combine the step1 and step2 to get the ClF3 Lewis Structure.
The ClF3 Lewis structure is a diagram that illustrates the number of valence electrons and bond electron pairs in the ClF3 molecule. The geometry of the ClF3 molecule can then be predicted using the Valence Shell Electron Pair Repulsion Theory (VSEPR Theory), which states that molecules will choose the ClF3 geometrical shape in which the electrons have from one another.
Finally, you must add their bond polarities to compute the strength of the three Cl-F bonds (dipole moment properties of the ClF3 molecule). The chlorine-fluorine bonds in chlorine trifluoride(ClF3), for example, are polarised toward the more electronegative fluorine in ClF3 molecule, and because both bonds have the same size and located around three fluorine terminals of the trigonal bipyramidal with two lone pairs (in total four electron) on the chlorine atom, their sum of dipole moment is nonzero due to the ClF3 molecule’s bond dipole moment and more electron polarity to the fluorine atoms. Because each three Cl-F bonds polarity not canceled each other in the ClF3 molecule. The trifluoro chlorine or chlorine trifluoride(ClF3) molecule is classified as a polar molecule.
The molecule of chlorine trifluoride (with trigonal bipyramidal molecular geometry) is tilted, the bond angles between chlorine and fluorine are 87.5 degrees. It has a difference in electronegativity values between chlorine and fluorine atoms, with central chlorine’s pull being less than terminal fluorine’s in the ClF3 molecule. But they canceled each other due to the asymmetrical molecular geometry of the ClF3 molecule.
As a result, it has the nonzero dipole moment. The ClF3 molecule has a nonzero dipole moment due to an unequal charge distribution of negative and positive charges. But both these atoms fall on the halogen family group. The fluorine atom is a more electronegative value than chlorine in the ClF3 molecule. The net dipole moment of the ClF3 molecule is higher than BrF3 molecule.
Molecules can be classified as polar or nonpolar. The molecule polar behaves in a different manner as compared to nonpolar.
Overview: ClF3 Lewis Structure
The central atom is chlorine, which is bordered on three terminals with fluorine atoms( in distorted T-shaped or trigonal bipyramidal), and two lone pairs on the central in the trigonal bipyramidal geometry. Chlorine has seven outermost valence electrons, indicating that it possesses seven electrons in its outermost shell, whereas fluorine also has seven valence electrons in its outermost shell. To complete the octet of the chlorine and fluorine atoms requires one valence electron on each of their outermost shell.
Three fluorine atoms establish covalent connections with the central chlorine atom as a result, leaving the chlorine atom with two lone pairs. There are two lone pairs of electrons on the chlorine central atom that resists the bond pairs of the three Cl-F. According to VSEPR theory, the Cl-F bond pairs polarity lead the ClF3 molecule to take on the distorted T-Shape or trigonal bipyramidal geometry structure.
The ClF3 molecule’s three Cl-F bonds are arranged in unsymmetrical polarity order around the trigonal bipyramidal molecular geometry, giving rise to the ClF3 molecular shape. The ClF3 molecule has a distorted T- shaped or trigonal bipyramidal molecular geometry because there is electrical repulsion between the lone pairs of electrons in fluorine and three bond pairs(Cl-F) of the ClF3 molecule.
Lewis structure of ClF3 has dot electron representative structure. Valence electrons of atoms undergo orbitals mixing in the chemical reactions, gives new types of molecular species. The molecule is nothing but a bundle of valence electrons from the atoms. But it is converted to bond pairs and lone pairs in the molecular structure.
Electronegative value Difference Calculation of ClF3 Molecule:
Chlorine and Fluorine Electronegative difference in ClF3:
The chlorine atom has an electronegativity of 2.96, while fluorine has an electronegativity of 3.98 in the ClF3 molecule. The difference in electronegativity of chlorine and fluorine can be estimated using the method below.
The electronegative value difference between chlorine and fluorine
Electronegativity value of chlorine = 2.96
Electronegativity value of fluorine= 3.98
Difference of electronegativity value between chlorine and fluorine= 3.98 – 2.96=1.02Electronegativity difference between Cl-F bond calculation of ClF3 molecule
The electronegative difference between chlorine and fluorine is greater than 0.5. This indicated the bond polarity moves near to polar nature. Cl-F bond polarity in the ClF3 molecule is polar.
Because of this difference in electronegativity of chlorine and fluorine atoms, the ClF3 molecule’s Cl-F bond becomes polar. The total net dipole moment of the ClF3 molecule is nonzero due to the no cancellation of the bond dipole moment in the distorted T-shaped or trigonal bipyramidal geometry. The electronegativity of an atom is the strength with which it may attract bound electron pairs to its side. The polarity of ClF3 is discussed in our previous post.
As a result, the Cl-F bond’s dipole moment is high due to the polarization of the bonds and two lone pairs of electrons on chlorine, and all Cl-F bonds’ dipoles are arranged in the asymmetrical ClF3 molecular geometry. The ClF3 molecule’s total dipole moment is predicted to be higher than the IF3 molecule.
The electron dot structure of the ClF3 molecule is also known as the ClF3 Lewis structure. It determines the number of outermost valence electrons as well as the electrons engaged in the ClF3 molecule’s bond formation. The outermost valence electrons of the ClF3 molecule must be understood while considering the Lewis structure of the molecule.
The chlorine atom is the middle element in ClF3 molecular geometry, with seven electrons in its outermost valence electron shell, whereas the fluorine atom has seven electrons in its outermost valence electron shell. The fluorine atom has seven valence electrons.
The ClF3 has a total of 28 valence electrons as a result of the foregoing above-said reasoning. With the core central chlorine atom, the three terminals with three fluorine atoms form covalent bonds, leaving the chlorine atom with two lone pairs in the middle of distorted T-shaped or trigonal bipyramidal geometry.
Because lone pair on the terminal fluorine atom creates interaction with Cl-F bond pairs(but it is negligible). The bond angle of the F-Cl-F bond in the distorted T- shaped or trigonal bipyramidal molecular geometry is approximately 86.2 degrees. This angle is smaller than the CH4 molecule bond angle. The Cl-F bond length is shorter than the Br-F bond length in BrF3 molecule.
To sketch the ClF3 Lewis structure by following these instructions:
Step-1: ClF3 Lewis dot Structure by counting valence electrons on the chlorine atom
To calculate the valence electron of each atom in ClF3, look for its periodic group from the periodic table. The halogen group families, which are the 17th group in the periodic table, are both made up of chlorine and fluorine atoms. In their outermost shells, fluorine and chlorine have seven valence electrons.
Calculate the total number of valence electrons in the ClF3 molecule’s outermost valence shell. The first step is to determine how many electrons are in the ClF3 Lewis structure’s outermost valence shell. An electron in an atom’s outermost shell is known as a valence electron. It is represented by dots in the ClF3 Lewis diagram. The ClF3 molecule’s core chlorine atom can be represented as follows:
Total outermost valence shell electron of chlorine atom in ClF3= 7
Total outermost valence shell electron of fluorine atom in ClF3= 7
The ClF3 molecule has one central chlorine and three fluorine atoms. Then the total outermost valence shell electrons can be calculated as follows
∴ Total outermost valence shell electrons available for ClF3 Lewis structure( dot structure) = 7+3*7=28 valence electrons in ClF3.calculation of total valence electron of ClF3 molecule
Choose the atom with the least electronegative value atom and insert it in the center of the molecular geometry of ClF3. We’ll choose the least electronegative value atom in the ClF3 molecule to place in the center of the ClF3 Lewis structure diagram in this phase. The electronegativity value in periodic groups grows from left to right in the periodic table and drops from top to bottom.
The first step is to put seven valence electrons around the chlorine atom as given in the figure.
Step-2: Lewis Structure of ClF3 for counting valence electrons around the terminal fluorine atoms
As a result, chlorine is the second atom in the periodic table’s halogen family group. Fluorine is the first member of the halogen family. The electronegative value of the fluorine atom is higher than that of the chlorine atom in the ClF3 molecule. Furthermore, fluorine has a seven electrons limit since chlorine is the less electronegative element in the ClF3 molecule.
In the ClF3 Lewis structure diagram, the chlorine atom can be the center atom of the molecule. As a result, central chlorine in the ClF3 Lewis structure, with all three fluorine atoms arranged in distorted T-shaped or trigonal bipyramidal geometry.
Add valence electrons around the fluorine atom, as given in the figure.
Step-3: Lewis dot Structure for ClF3 generated from step-1 and step-2
Connect the exterior and core central atom of the ClF3 molecule with three single Cl-F bonds. In this stage, use three fluorine atoms on the outside of the ClF3 molecule to the central chlorine atom in the middle.
Count how many electrons from the outermost valence shell have been used in the ClF3 structure so far. Each Cl-F bond carries two electrons because each chlorine atom is connected to three fluorine atoms by three Cl-F bonds. Bond pairings of Cl-F are what they’re called.
So, out of the total of 28 valence electrons available for the ClF3 Lewis structure, we used 6 electrons for the ClF3 molecule’s three Cl-F bonds. The ClF3 molecule has two lone pairs of electrons in the central chlorine atom.
Place the valence electrons in the Cl-F bond pairs starting with the core chlorine, three fluorine atoms in the ClF3 molecule. In the ClF3 Lewis structure diagram, we always begin by introducing valence electrons from the central chlorine atom(in step1). As a result, wrap around the central chlorine atom’s bond pair valence electrons first (see figure for step1).
The chlorine atom in the molecule gets only six electrons around its molecular structure. This central chlorine atom is extra octet stable. But it has two lone pairs. chlorine(Cl2) is a blue color gas in nature. when chlorine acted as chlorinating agent, it is used as a chemical reagent. But ClF3 is used as a fluorinating agent in organic chemistry.
Chlorine requires 10 electrons in its outermost valence shell to complete the molecular extra octet stability, 6 electrons bond pairs in three Cl-F bonds. Then lone pairs of electrons on the fluorine atoms of the ClF3 molecule are placed in a distorted T-shaped or trigonal bipyramidal geometry. Chlorine already shares six electrons to the three Cl-F bonds. Then place the valence electron in the fluorine atoms, it placed around seven electrons on each atom(step-2). 18 valence electrons placed around fluorine atoms as lone pairs of electrons.
We’ve positioned 18 electrons around the terminal fluorine atoms(step-3), which is represented by a dot, in the ClF3 molecular structure above. The chlorine atom completes its molecular extra octet stability in the ClF3 molecule because it possesses six electrons in its (three Cl-F) bond pairs with three fluorine in the outermost valence shell.
Count how many outermost valence shell electrons have been used so far using the ClF3 Lewis structure. Three electron bond pairs are shown as dots in the ClF3 chemical structure, whereas three single bonds each contain two electrons. The outermost valence shell electrons of the ClF3 molecule(bond pairs) are six as a result of the calculation.
So far, we’ve used 28 of the ClF3 Lewis structure’s total 28 outermost valence shell electrons. Two lone pairs of electrons on the chlorine atom in the distorted T structure or trigonal bipyramidal of the ClF3 molecule.
Complete the middle chlorine atom stability and, if necessary, apply a covalent bond. The central chlorine atom undergoes extra octet stability(due to two lone pairs of electrons).
The core atom in the ClF3 Lewis structure is chlorine, which is bonded to the three fluorine atoms by single bonds (three Cl-F). With the help of three single bonds, it already shares six electrons. As a result, the chlorine follows the extra octet rule and has six electrons surrounding it on the three terminals of the ClF3 molecule’s trigonal bipyramidal geometry.
How to calculate the formal charge on chlorine and fluorine atoms in ClF3 Lewis Structure?
Calculating formal charge on the chlorine of ClF3 molecule:
The formal charge on the ClF3 molecule’s chlorine central atom often corresponds to the actual charge on that chlorine central atom. In the following computation, the formal charge will be calculated on the central chlorine atom of the ClF3 Lewis dot structure.

In the Lewis structure of ClF3, the formal charge on the terminal fluorine atom is zero.
In this post, we discussed the method to construct the ClF3 Lewis structure. First, the valence electrons are placed around the chlorine atom. Second, place the valence electron on the fluorine atoms. Finally, when we combined the first and second steps. It gives ClF3 Lewis structure. Need to remember that, if you follow above said method, you can construct molecular dot structure very easily.
