Assertion (A) Complexes of MX(6) and MX(...

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.

A

Both A and R are true but R is the correct expanation of A

B

Both A and R are true but R is NOT the correct expanation of A

C

A is true but R is false

D

A is false and R is true

Text Solution

Verified by Experts

The correct Answer is:
B
For complexes of `MX_(6)` and `MX_(5)L` type, different geometric arrangements of the ligands are not possible due to presence of plane os symmetry.
