Q. How many of the following compounds have optical isomers?
(I) $\left[Co\left(en\right)_{3}\right]Br_{3}$
(II) $\left[Co\left(en\right)_{2} Br_{2}\right]Br$
(III) $\left[Co\left(NH_{3}\right)_{3} Br_{3}\right]$
(IV) $\left[Co\left(en\right)\left(NH_{3}\right)_{2} Br_{2}\right]Br$

Coordination Compounds

Solution:

$\left[Co\left(NH_{3}\right)_{3} Br_{3}\right]$ shows optical isomerism.
