Shape and hybridization of `IF_5`, respectively, are

Options

A. Trigonal bipyramidal, `sp^3 d`
B. Sea saw, `sp^3d`
C. Square pyramidal, `sp^3 d^2`
D. Pentagonal pyramidal, `sp^3 d^3`

Answer

C

Explanation

Count the no. of bond pairs and lone–pair around the central atom.
`IF_5` : Summation of group number = 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.
