Question

the geometry of electron pairs around I in IF5 is

Answer 1

The molecular geometry of IF5 is square pyramidal with asymmetric charge distribution on the central atom.

Answer 2

In IF5, considering I to be the central atom, it has 7 valence electrons.

5 of them form Sigma covalent bonds with 5,F atoms. and 2 electrons form a lone pair of electrons.

There fore the steric number= no. of sigma bonds+lone pairs.

=5+1=6.

There for the hybridisation is sp3d2 (6 hybrid orbitals)

Thus it's configuration is Octahedral. However this contains a lone pair of e which are not counted in the structure or geometry.

There for this forms a Pyramidal structure with a lone pair.
