Q. The number of possible optical isomers for the complexes $MA_{2}B_{2}$ with $sp^{3}$ and $dsp^{2}$ hybridized metal atom, respectively, is

Note: A and B are unidentate neutral and unidentate monoanionic ligands, respectively.

Solution:

As in $MA_{2}B_{2}$ tetrahedral structure which is $sp^{3}$ hybridised, the central metal is not chiral hence it does not show optical isomers.

In the case of square planar that is $dsp^{2}$ hybridised, two geometrical isomers will form but not optical isomers.
