For the given complex `[CoCl_(2)(en)(NH_(3))_(2)]^(+)`, the number of geometrical isomers, the number of optical isomers and total number of isomers of all type possible respectively are

Options

A. 2, 2 and 4
B. 2, 2 and 3
C. 2, 0 and 2
D. 0, 2 and 2

Answer

B

Explanation

(i) Geometrical isomers have same structural formula but differ in spatial arrangement of groups around the double bond. (ii) Different arrangement of atoms or groups in three dimensional space results in two optical isomers which are images of each other.

Therefore, number of geometrical isomers, optical isomers and total number of isomers are 2, 2 and 3 respectively.
