Question

Which of the following compounds shows optical isomerism?

$CH_{3}-CH-BrCOOH$

$CH_{2}OHCH_{2}-COOH$

$COOHCHBr-COOH$

$CH_{2}Br-CH_{2}-COOH$

Answer

$CH_{3}-CH-BrCOOH$

Explanation

Solution

Optical isomerism is exhibited by asymmetric compounds. Compounds having chiral carbon atom are usually asymmetric and exhibit optical isomerism. $CH_{3}\overset{*}{C}H(Br)COOH$ , due to the presence of chiral carbon atom, exhibits optical isomerism. [ $\overset{*}{C}=$ chiral carbon, the carbon four valencies of which are attached with four different groups.]
