For the given complex `[CoCl_(2)(en)(N_(3))_(2)]^(+)`, the number of geometrical iosmers, 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 1

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 isomers . Out of these , cis isomer will be optical active and shows two d & l forms . So the total number of possible isomers will be three .
