$CH_{3}CH_{2}OCH_{2}CH_{3}$ and $CH_{3}OCH_{2}CH_{2}CH_{3}$

Vedclass · Answer

(D) Metamerism arises due to the difference in the nature of alkyl groups attached to the same polyvalent functional group (like $-O-$, $-S-$, $-NH-$, $-CO-$). In option $(D)$, both molecules are ethers with the same molecular formula $C_{4}H_{10}O$. $CH_{3}CH_{2}OCH_{2}CH_{3}$ is diethyl ether, where the oxygen atom is attached to two ethyl groups. $CH_{3}OCH_{2}CH_{2}CH_{3}$ is methyl propyl ether, where the oxygen atom is attached to one methyl group and one propyl group. Since the distribution of alkyl groups around the oxygen atom is different, they are metamers.

Which of the following pairs of molecules are metamers?
