1.	A metal ion M^(n+) having d^(4) valence electronic configuration combines with three didentate ligands to form a complex compound. Assuming Delta_(0) gt P (i) Draw the diagram showing d orbital splitting during this complex formation. (ii) Write the electronic configuration of the valence electrons of the metal M^(n+) ion in terms of t_(2g) and e_(g) (iii) What type of hybridisation will M^(n+) ion have ? (iv) Name the type of isomerism exhibited by this complex.
Answer» SOLUTION :(i) If `Delta_(0) gt P`, pairing will occur in the `t_(2g)` orbitals and `e_(g)` orbitals will remain vacant (ii) `t_(2g)^(4) e_(g)^(0)` (iii) `d^(2)SP^(3)` (as there are three didentate ligands to combine) (iv) `[M(A A)_(3)]` type complexes show optical isomerism.
