Identify the optically active compounds from the following
(a) $[C o (e n)_{3}]^{3 +}$
(b) $t r a n s - [C o (e n)_{2} C l_{2}]^{+}$
(c) $c i s - [C o (e n)_{2} C l_{2}]^{+}$
(d) $[C r (N H_{3})_{5} C l]$

Solution

$[C o (e n)_{3}]^{3 +}$ and $c i s - [C o (e n)_{2} C l_{2}]^{+}$ are optically active compounds because their mirror images are non-superimposable isomer.

Hence, (a) and (c) are correct choices.
