Current Question (ID: 18712)

Question:

$\text{Optical isomerism is exhibited by among the following is/are:}$

Options:

1. $[\text{Cr(Ox)}_3]^{3+}$
2. $[\text{PtCl}_2(\text{en})_2]^{2+}$
3. $[\text{Cr(NH}_3)_2\text{Cl}_2\text{en}]^{+}$
4. $\text{All of the above}$

Solution:

$\text{HINT: In optical isomerism, mirror images are non-superimposable.}$ $\text{Explanation: Optical isomerism occurs when a molecule is not superimposable with its mirror image.}$ $1. \text{Optical isomers of } [\text{Cr(Ox)}_3]^{3+}:$ $2. \text{Optical isomers of } [\text{PtCl}_2(\text{en})_2]^{2+}:$ $3. \text{Optical isomers of } [\text{Cr(NH}_3)_2\text{Cl}_2\text{en}]^{+}:$ $\text{It forms three geometrical isomers and one isomer is optical active hence, a total 4 stereoisomers.}$
