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.

Options

A. Statement-1 and statement-3 are correct
B. Statement-1 and statement-3 are correct
C. Statement-1 is incorrect
D. Statement-2 and statement-3 are incorrect

Answer

B, C

Explanation

(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"`.
