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

The octahedral complex of the type `[M(A A)X_(2)Y_(2)]`, i.e., `[CoCl_(2)(en)(NH_(3))_(2)]^(+)` will show two cis- and trans-geometrical isomers. Out of these, cis-isomer will be optically active and shows two d- and l-forms. So the total number of possible isomers will be three.
