Identify the correct statement about ClF3\text{ClF}_3 from the following options :

Options

  1. AIt has T-shaped geometry with two lone pairs on Cl atom.
  2. BIt has T-shaped geometry with three lone pairs on Cl atom.
  3. CIt has a trigonal pyramidal geometry with two lone pairs on Cl atom.
  4. DIt has a planar trigonal geometry with two lone pairs on Cl atom.

Correct answer

A. It has T-shaped geometry with two lone pairs on Cl atom.

Step-by-step solution

The central atom in ClF3\text{ClF}_3 is Chlorine (Cl).

Number of valence electrons of Cl = 77.

Number of monovalent atoms (F) attached = 33.

Steric number = 12(7+3)=5\dfrac{1}{2}(7 + 3) = 5.

The hybridization of the central atom is sp3dsp^3d.

Number of bond pairs = 33.

Number of lone pairs = 5−3=25 - 3 = 2.

The electron geometry is trigonal bipyramidal. According to VSEPR theory, to minimize repulsion, the two lone pairs occupy the equatorial positions.

This results in a T-shaped molecular geometry.

Therefore, ClF3\text{ClF}_3 has a T-shaped geometry with two lone pairs on the Cl atom.

Answer: It has T-shaped geometry with two lone pairs on Cl atom.
