The shape of \[I{{F}_{7}}\]molecule is

A)  Pentagonal bipyramidal

B)  Tetrahedral

C)  Trigonal bipyramidal

D)  Octahedral

Correct Answer: A

Solution :

Number of electron pairs around iodine in \[\text{I}{{\text{F}}_{\text{7}}}\]molecule is seven so the hybridization is \[s{{p}^{3}}{{d}^{3}}\]and the shape (geometry) is pentagonal bipyramidal. Hence, the correct option is (a).
