Metamerism arises due to the different alkyl chains on either side of a polyvalent functional group. — Alcohols Phenols and Ethers Chemistry Question

💡 Solution & Explanation

Diethyl ether ($C_2H_5-O-C_2H_5$) and Methyl propyl ether ($CH_3-O-C_3H_7$) have the same molecular formula ($C_4H_{10}O$) but differ entirely in the alkyl groups attached to the polyvalent ether oxygen. These are metamers.
