Q. The geometry of electron pairs around $ I $ in $IF _{5}$ is:

Chemical Bonding and Molecular Structure

Solution:

$IF _{5}=.7+5 \times 7=\frac{42}{8}=5+1$

$sp ^{3} d ^{2}$ hybridisation, hence it should be octahedral.

Due to the presence of one lone pair of electrons, its actual geometry is square pyramidal.
