Assertion: Complexes of MX6 and MX5L

Assertion: Complexes of MX6 and MX5L type (X and L are unidentate) do not show geometrical isomerism.

Reason: Geometrical isomerism is not shown by complexes of coordination number 6.

(i) Assertion and reason both are true, the reason is the correct explanation of

assertion.

(ii) Assertion and reason both are true but the reason is not the correct

explanation of assertion.

(iii) An assertion is true, the reason is false.
