`PCl_5` has a shape of trigonal bipyramid whereas `IF_5` has the shape of a square pyramid. It is due to

A

presence of unshared electron pair on I which is oriented so as to minimise repulsion while P in `PCl_5` has no unshared pair

B

octet of P is complete while that of I is incomplete

C

P and I are of different groups

D

F and Cl have different extent of repulsion

Text Solution

Verified by Experts

The correct Answer is:
A
presence of unshared electron pair on I which is oriented so as to minimise repulsion while P in `PCl_5` has no unshared pair
