Q. Which of the following does not have optical isomer?
A) $\left\lbrack Co(en)\left( NH_{3} \right)_{2}Cl_{2} \right\rbrack Cl$
B) $\left\lbrack Co(en)_{2}Cl_{2} \right\rbrack Cl$
C) $\left\lbrack Co\left( NH_{3} \right)_{3}Cl \right\rbrack$
D) $\left\lbrack Co(en)_{3} \right\rbrack Cl_{3}$
Explanation
(c)
$\left\lbrack Co\left( NH_{3} \right)_{3}Cl_{3} \right\rbrack\$does not have optical isomers because it is of formula $MA_{3}B_{3}$ which does not show optical isomerism
