उत्तर
The strength of the intermolecular interactions in organic molecules determines their boiling points. These forces consist of van der Waals forces and dipole-dipole interactions and depend on the molecular mass and surface area of the molecules. Compounds with higher molecular mass have higher boiling points. Thus, the correct order is:
Chloromethane < Bromomethane < Dibromomethane < Bromoform
