Question

Shape and hybridization of `IF_5`, respectively, are
A. Trigonal bipyramidal , `sp^(3)d`
B. Sea, Saw `sp^(3)d`
C. Square pyramidal `sp^(3)d^(2)`
D. Pentagonal pyramidal `sp^(3)d^(2)`

Answer 1

Correct Answer - C
Count the no. of bond pairs and lone -pair around the central atom.
`IF_(5)` : Summation of group nunber =42
Bond pairs =`42/8=5` (Residue 2)
Lone pair =`2/2=1`
5 bond pairs, 1 lone pair means the geometry is square pyramidal
