`[Co(en)_3]^(3+)` ion is expected to show

A

(a) two optically active isomers: d and l forms

B

(b) d, l and meso forms

C

(c) four optically active isomers: cis, d and l isomers and trans d and l isomers

D

(d) none of these

Text Solution

Verified by Experts

The correct Answer is:
A
`[Co(en)_3]^(3+)` ion due to absence of one of the symmetry elements it has two d-and l-optically active forms.
