Vedclass · Answer

(B) Metamerism arises due to the difference in the alkyl chains attached to the same polyvalent functional group.In option $A$,the functional group is $-CO-NH-$. In the first compound,the groups attached are $C_6H_5$ and $CH_3$. In the second compound,the groups attached are $CH_3$ and $C_6H_5$. These are identical,not metamers.In option $B$,the functional group is $-CO-O-CO-$. In the first compound,the groups attached are $C_2H_5$ and $C_2H_5$. In the second compound,the groups attached are $CH_3$ and $C_3H_7$. Since the alkyl groups attached to the central functional group differ,they are metamers.Therefore,only option $B$ represents a pair of metamers.
