The type of isomerism shown by the complex \[\text{ }\!\![\!\!\text{ CoC}{{\text{l}}_{\text{2}}}{{\text{(en)}}_{\text{2}}}\text{ }\!\!]\!\!\text{ }\] is            [NEET - 2018]

A) Ionization isomerism

B) Coordination isomerism

C) Geometrical isomerism

D) Linkage isomerism

Correct Answer: C

Solution :

[c] In \[\text{ }\!\![\!\!\text{ CoC}{{\text{l}}_{\text{2}}}{{\text{(en)}}_{\text{2}}}\text{ }\!\!]\!\!\text{ }\], Coordination number of Co is 6 and this compound has octahedral geometry.

As per given option, type of isomerism is geometrical isomerism.
