Solution

The correct option is B b
Option a)- Structure of $I F_{5}$ is square pyramidal

Option b)- In $B r F_{3}$ , Bromine atom is $s p^{3} d$ hybridized. The two lone pairs will occupy the equatorial positions to minimise lone pair-lone pair and the bond pair- lone pair repulsions which are greater than the bond pair-bond pair repulsions. In addition, the axial fluorine atoms will be bent towards the equatorial fluorine in order to minimise the lone-pair-lone pair repulsions. The shape would be that of a slightly bent 'T'.

Option c)- Structure of $X e O F_{4}$ is Square pyramidal.

Option d)- Structure of $X e F_{4}$ is Square planar.
