Q.
Which one of the following will show optical isomerism?
WBJEEWBJEE 2011Organic Chemistry – Some Basic Principles and Techniques
Solution:
$2$-hydroxypropanoic acid has a central carbon atom, which is linked to four different groups. This carbon atom is called chiral carbon atom and the molecule is called chiral molecule. Hence, $2$-hydroxy propanoic acid shows optical isomerism.
