Question

In which of the following molecules all A - X bond lengths are identical? [A = central atom and X = surrounding atom], X e F 4, P F 5, Both A and B, S F 4

MARKS App · Accepted Answer

Hybridisation of Xe → s p 3 d 2 All four X e - F bonds are of equal lengths as they lie in the same plane and are at 90 ° apart from each other. Hybridisation → s p 3 d ( P - F ) a x i a l > ( 1.58 Å ) ( P - F ) e q u a t o r i a l ( 1.53 Å ) Hybridisation → s p 3 d ( S - F ) a x i a l > ( S - F ) e q u a t o r i a l
