Q. Which one of the following has highest number of isomers?
A) $\left\lbrack Co\left( NH_{3} \right)_{5}Cl \right\rbrack^{2 +}$
B) $\left\lbrack Co(en)_{2}Cl_{2} \right\rbrack^{+}$
C) $\lbrack Ru\left( NH_{3} \right)_{4}Cl^{-}\rbrack$
D) $\left\lbrack In\left( PP_{3} \right)_{2}H(CO) \right\rbrack^{2 +}$
Explanation
(b)
$\left\lbrack Co(en)_{2}Cl_{2} \right\rbrack^{+}\$shows geometrical as well as optical isomerism
