Out of the following two coordiantion entities which is chiral (optically active) ?
(a) `cis-[CrCl_(2)("ox")_(2)]^(3-)`
(b) trans - `[CrCl_(2)("ox")_(2)]^(3-)`

Text Solution

Verified by Experts

The two geometrical isomers (a) and (b) are of the type `[M(AA)_(2)b_(2)]^(n+-)` , so (a) cis-isomer is chiral (optically active) The two entities are represented as

Trans form is optically inactive due to the presence of plane of symmetry as shown
