Select the correct decreasing order of boiling points of compounds from the following.

Step-by-step solution

Intermolecular forces dictate boiling points, with London dispersion forces dominating as molecular mass increases due to stronger temporary dipoles. All compounds are polar, exhibiting dipole-dipole interactions, but mass is the primary factor here. Molecular masses are calculated as: CH ₃ Cl = 50.5 g/mol, CH ₃ Br = 95 g/mol, CH ₂ Br ₂ = 174 g/mol, CHBr ₃ = 253 g/mol Boiling point increases with molecular mass, so the decreasing order is: CHBr ₃ > CH ₂ Br ₂ > CH ₃ Br > CH ₃ Cl Option D matches this sequence.
