The number of possible optical isomers for the complexes M A 2 B 2 with s p 3 and d s p 2 hybridized metal atom, respectively, is: Note: A and B are unidentate neutral and unidentate monoanionic ligands, respectively.

Step-by-step solution

If the complex MA 2 B 2   is    sp 3 hybridised then the shape of this complex is tetrahedral this structure is optically inactive due to the presence of plane of symmetry Optical isomers = 0 (b) If the complex MA 2 B 2   is     dsp 2 hybridised then the shape of this complex is square planar. Both isomers are optically inactive due to the presence of plane of symmetry. Optical isomers = 0
