The structure of \[\text{I}{{\text{F}}_{\text{5}}}\]can be described as

A)  

B)  

C)

D)   None of these

Correct Answer: C

Solution :

 Number of hybrid orbitals = number of \[bp+\]number of \[lp\] \[=5+1=6\] Thus, hybridisation is \[\text{s}{{\text{p}}^{\text{3}}}{{\text{d}}^{\text{2}}}\]but geometry due  to the presence of one lone pair is square pyramidal.
