Question

Both geometrical and optical isomerisms are shown by

• A. $\left[ Co (e n)_{2} Cl _{2}\right]^{+}$
• B. $\left[ Co \left( NH _{3}\right)_{5} Cl \right]^{2+}$
• C. $\left[ Co \left( NH _{3}\right)_{4} Cl _{2}\right]^{+}$
• D. $\left[ Cr (o x)_{3}\right]^{3-}$

Answer 1

Answer: (A)

$\left[ Co (e n)_{2} Cl _{2}\right]^{+}$ canshow bothtypes ofstereoisomerism.





$I $ and $ II$ are optical isomers while $I$ and $III, II$ and $III$ are geometrical isomers.
