Correct answer: D
To match the disinfectant by-products with their chemical compositions, we analyze the nomenclature based on standard organic chemistry rules. Dibromochloromethane contains two bromine atoms and one chlorine atom attached to a methane backbone, corresponding to CHBr₂Cl (I). Bromoform is another name for tribromomethane, which has three bromine atoms, matching CHBr₃ (IV). Bromodichloromethane consists of one bromine and two chlorine atoms, corresponding to CHBrCl₂ (III). Finally, Chloroform is trichloromethane with three chlorine atoms, matching CHCl₃ (II). Therefore, the correct matching sequence is A–I, B–IV, C–III, D–II.
