A metal ion M<sup
(i) If Δ0 > P, pairing of d4 ion will occur in the t2g orbitals and eg orbitals will remain vacant.
Thus, the electronic configuration is t42g e0g
(ii) hybridization is d2sp3 (as there are three didentate ligands to combine)
(iii) As there are three didentate ligands. Hence type is [M(AA)3]. This type of complexes shows optical isomerism.
Note: Optical isomerism is an isomerism in which the optical isomers rotate the plane of polarized light in the opposite direction means he two isomers which are structurally non-superimposable mirror image of each other (they do not possess the plane of symmetry)
