For the given complex `[CoCl_2 (en)(NH_3)_2]^(+)`, the number of geometrical isomers, the number of optical isomers and total numbềr 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_2Y_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 acitve and show two d and l forms. So the total number of possible isomers will be three.
