The chemistry formula ClF3 to represent Chlorine Trifluoride. It is one interhalogen compound. 

ClF3 is colorless together gas and condenses into a pale green-yellow liquid. The link is extremely reactive, poisonous, and corrosive. Chlorine Trifluoride has actually been provided in a selection of applications since it was first discovered. 

The fluorination the Chlorine was first reported to develop ClF3. It reacts with steels to kind Chlorine and Fluorine based halides. Examples incorporate Phosphorous Trichloride (PCl3) and Phosphorous Pentafluoride (PF5). It violently reacts with water to give Hydrogen Chloride or Hydrogen Fluoride. Oxygen is additionally released.

Chlorine Trifluoride is primarily used in the semiconductor sector as a cleaning agent. Its usage as a storable oxidizer in rockets has actually been proposed. However, concerns relating come storage have actually not been addressed. 

ClF3 is hypergolic while also being a very strong oxidizing and fluorinating agent. The is oftentimes incendiary and also can cause far-reaching harm if offered abhorrently. The is necessary to take it due precautions when taking care of hazardous compounds.

ClF3 has actually the following properties:

Name the the moleculeChlorine Trifluoride (ClF3) 
No. Of valence electrons7 + (7 x 3) = 28 valence electrons
Hybridization the the main atomsp3d
Bond Angles87.5°
Molecular Geometry of ClF3T-shaped molecule Geometry

ClF3 Valence Electrons

Valence electrons space those electrons the are obtainable for exchanges and also bond formation. Lock are current in the atom’s outermost shell, wherein the pressure of attraction native the cell core is relatively less. This, in turn, renders these electron readily obtainable upon excitation. 

Before jumping into the Lewis structure, us must very first determine how countless valence electrons are available to us. Each constituent atom in the molecule contributes valence electrons from your outermost shells.

Chlorine Trifluoride comprises three Fluorine atoms and one Chlorine atom.

Being in team 7 the the periodic table, Chlorine has seven valence electrons through a valency that -1. Chlorine’s digital configuration is offered by 3s23p5.

Therefore, the Chlorine atom contributes 7 x 1 = 7 valence electrons.

Fluorine is in group 17 that the routine table with the electronic configuration 2s22p5. Therefore, the 3 Fluorine atoms current contribute: 7 x 3 = 21 Valence Electrons.

Therefore, the total number of valence electron in ClF3 is offered by:

7 + 21 = 28 Valence Electrons

ClF3 Lewis Structure

Now the we know the variety of valence electrons, us can type covalent bonds and distribute the electrons in accordance with the octet rule. 

There room a full of 28 valence electrons accessible to us. Chlorine acts together the main atom v the Fluorine atoms neighboring it. 

We then kind covalent bonds in between the central Chlorine atom and also the bordering Fluorine atom using several of the valence electrons easily accessible to us. 

We then usage the continuing to be valence electrons to to fill up the octets that the bordering Fluorine atoms. This is presented in the figure below.


24 valence electrons have been used. Us observe the there space two lone pairs of electron left over. These two lone pairs affix themselves come the central Chlorine atom as displayed in the figure.

This framework looks unusual. To verify that stability, let us calculate the formal charges for the ClF3 molecule. 

Formal charges because that an element/structure assist determine its most stable Lewis framework state. The is determined such that the elemental fee on each atom is closest come zero.

FC = Valence electron – Non-bonding electron – (Bonding electrons ÷ 2)

In this case,




The formal charges being 0 for every one of the atom in the molecule tells us that the framework shown over is stable. 

The Lewis framework for ClF3 is given below:


ClF3 Hybridization

Chlorine Trifluoride comprises 3 Fluorine atoms, all pulled together by the central Chlorine atom. To recognize the hybridization, we take a look at the Lewis structure of the ClF3 molecule. 

There are two lone pairs on the central Chlorine atom. Chlorine also forms covalent bonds through the neighboring Fluorine atoms.

All in all, there space three Cl-F bonds and two lone pairs of electrons. 

To kind bonds with Fluorine, the central Chlorine atom needs 3 unpaired electrons. 

One 3s orbital, three 3p orbitals, and also one 3d orbital participate in the hybridization process. This then leads come the development of 5 sp3d orbitals. 

Therefore, the hybridization the the main Chlorine atom in Chlorine Trifluoride is sp3d.

ClF3 bond Angles


Due to the existence of lone pairs, the constituent atom repel each other in accordance v the VSEPR theory. The bond angle in ClF3 room 87.5°.

ClF3 molecular Geometry and also Shape

To recognize the molecular geometry for Chlorine Trifluoride, us go back to that Lewis structure. Indigenous the Lewis structure, it deserve to be observed that Chlorine has an expanded octet. It has actually two lone bag attached come it. 

There space three Fluorine atoms surrounding the central Chlorine atom as well. We can visualize the same and determine the molecular geometry.


According to the VSEPR theory, the Fluorine atoms will certainly repel each other. Place the three Fluorine atoms on the central Chlorine atom provides us a Trigonal Planar geometry.

However, upon including the two lone bag of electrons, it alters into a T-shaped molecule geometry. 

The electronic geometry is Trigonal Bipyramidal. 

Therefore, ClF3 has a T-shaped molecule geometry and also a Trigonal Bipyramidal electronic shape.
