Solution

The correct option is B 4
$C l F_{3}$ is $s p^{3} d$ hybridized. It has 3 bond pair and 2 lone pair. Shape is trigonal bipyramidal with lone pair in the equatorial plane. Each lone pair is forming nearly 90 degree angle with axial fluorine. Hence, number of lp-bp repulsion $=$ 4.

Q. Hybridization is the chemist's attempt to explain the observed molecular shape by constructing hybridized atomic orbitals with the appropriate inter orbital angles. The molecule for which deviation from a normal bond angle is observed,

theory suggests electron pair repulsive interaction (

). While from hybridization point of view that is a departure from normal hybridization because the angle between any equivalent hybrid orbitals determines the fraction of s and p characters of the hybrid and vice-versa.
