The phenomenon of metamerism is shown by

(a) Ethyl alcohol and dimethyl ether

(b) Methyl n-propyl ether and diethyl ether

(c) Acetone and propionaldehyde

(d) Propionic acid and acetic acid

Answer 1

Correct option is (b) Methyl n-propyl ether and diethyl ether

Methyl propylether and diethyl ether. Both of these compounds belong to the class of ethers. In methyl propylether, the carbon skeleton consists of a methyl group attached to a propyl group. In diethyl ether, the carbon skeleton consists of two ethyl groups. These compounds have the same molecular formula (C₅H₁₂O), but different structures.
