Question

what if maximum F-I-F angle in IF7​

Answer 1

Explanation:

In IF7

central atom is I

electronic configuration : 1s² 2s² 2p⁶ 3² 3p⁶ 4s² 3d¹ 4p⁶ 5s² 4d¹⁰ 5p⁵

7  atomic orbitals (one s, three p and three d orbitals) hybridize to form seven sp3d3 hybrid orbitals.

Hybrid orbitals  will overlap with singly filled 2pz atomic orbitals of seven F-atoms to form seven I-F sigma bond.

Geometry of IF7 : Pentagonal bipyramidal and

Bond angle is 72⁰ and 90⁰.
