Consider the following statements : Statement-1: Generally, square planar complexes show geometrical isomerism but do not exhibit optical isomerism because they do not possess plane of symmetry. Statement-2: Delta_(t)=(4)/(9) Delta_(0) Statement-3: In octahedral complexes each electron entering the t_(2g) orbitals stabilizes the complex ion by 0.4 Delta_(0) and each electron entering the e_(g) orbital destabilizes the complex by an amount of 0.6 Delta_(0). Select the correct statement from the codes given below.

1.	Consider the following statements : Statement-1: Generally, square planar complexes show geometrical isomerism but do not exhibit optical isomerism because they do not possess plane of symmetry. Statement-2: Delta_(t)=(4)/(9) Delta_(0) Statement-3: In octahedral complexes each electron entering the t_(2g) orbitals stabilizes the complex ion by 0.4 Delta_(0) and each electron entering the e_(g) orbital destabilizes the complex by an amount of 0.6 Delta_(0). Select the correct statement from the codes given below.
Answer» Statement-1 and statement-3 are correct Statement-1 and statement-3 are correct Statement-1 is INCORRECT Statement-2 and statement-3 are incorrect SOLUTION :(a) Square planar complexes have P.O.S. which is the molecular plane itself. (C ) `"CFSE" =-0.4 Delta_(0)xx"n"_("n"_(2g))+0.6 Delta_(0)xx"n"_("eq")+"nP"`.
