Q. The geometry of electron pairs around $ I $ in $IF _{5}$ is:
Chemical Bonding and Molecular Structure
A
Octahedral
44%
B
Trigonal Bipyramidal
15%
C
Square Pyramidal
35%
D
Pentagonal Planar
5%
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.
