Consider the following satements :
`S_(1): ` Generally square planare complexes show geometrical isomerism but do not exhibit optical isomerism because thy do not possess plane of symmetry .
`S_(2): Delta_(t)=(4)/(9)Delta_(0)`
`S_(3)`: In octahedral complexes each electron entering teh `t_(2g)` orbitals stabilizes the complex ion by 0.4 `Delta_(0)` and each electron entering teh `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. F T T
B. F F T
C. T F T
D. T T F

Answer

A

Explanation

`S_1`:has plane of symmetry, therefore, does not show optical isomerism.
`S_2` and `S_3` are correct statements.
