Current Question (ID: 18716)

Question:

$\text{The compound that gives a pair of enantiomorphs is:}$ $\text{(en = NH}_2 \text{CH}_2\text{CH}_2\text{NH}_2\text{)}$

Options:

1. $[\text{Co} (\text{NH}_3)_4\text{Cl}_2] \text{NO}_2$
2. $[\text{Cr} (\text{NH}_3)_6][\text{Co} (\text{CN})_6]$
3. $[\text{Co} (\text{en})_2\text{Cl}_2]\text{Cl}$
4. $[\text{Pt} (\text{NH}_3)_4][\text{PtCl}_6]$

Solution:

$\text{HINT: } [\text{Co} (\text{en})_2\text{Cl}_2]\text{Cl} \text{ will give a pair of enantiomorphs.}$ $\text{Explanation:}$ $\text{Enantiomorphs or enantiomers are a pair of compounds which are non}$ $\text{superimposable mirror images of each other.}$ $\text{The example is } [\text{Co} (\text{en})_2\text{Cl}_2]^+ \text{ Dichlorobis [ethylene diamine] cobalt (III) can}$ $\text{occur as enantiomorphs as shown below.}$ $\text{All other are optically inactive. So, there will be no enantiomers for those}$ $\text{complexes.}$
