Vedclass · Answer

(A) molecule is optically active if it contains at least one chiral center (a carbon atom bonded to four different groups).$A$. Lactic acid $(CH_3-CH(OH)-COOH)$ has a chiral carbon atom bonded to $-H$,$-OH$,$-CH_3$,and $-COOH$ groups. Thus,it is optically active.$B$. Propane $(CH_3-CH_2-CH_3)$ has no chiral center.$C$. Cyclohexane is a symmetric molecule and does not possess a chiral center.Therefore,the correct option is $A$.
