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

Assertion and reason both are true, reason is correct explanation of assertion.

B

Assertion and reason both are true but reason is not the correct explanation of assertion.

C

Assertion is true, reason is false.

D

Assertion is false, reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
Assertion and reason both are correct and reason is not correct explanation of assertion.
Complexes of `MX_(6)` and `MX_(5)L` type (X and L are unidentate) do not show geometrical isomerism due to presence of plane of symmetry and necessary condition for showing geometrical isomerism is that complex is must of `MA_(4)B_(2)` type or `[M (AB)_(2) X_(2)]` type
