Assertion (A) : Complexes of `MX_(6)` and `MX_(5)L` type (X and L are unidentate) do not show geometrical isomerism.
Reason (R) : Geometrical isomerism is not shown by complexes of coordination number 6.

Options

A. Both (A) and (R) are true and (R) is the correct explanation of (A)
B. Both (A) and (R) are true but (R) is not the correct explanation of (A)
C. (A) is true but (R) is false
D. (A) is false but (R) is true

Answer

C

Explanation

Correct reason : In `MX_(6)` and `MX_(5)L` type of complexes the relative positions of the ligands attached to the central metal atom are same with respect to each other.
