Describe the change in hybridisation or any of the Al atom in the following
reaction
AICI+CI-
AICI,​

Answer 1

The hybridization of Al atom changes from sp

2 in AlCl3 to sp3 in AlCl4−In AlCl3 , Al contains 3 bond pairs of electrons and zero lone pair of electrons.

Hence, it is sp2 hybridized. In AlCl4−, Al atom contains 4 bond pairs of electrons and zero lone pairs of electrons.

Hence, it is sp 3 hybridized.
