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

Assertion: The boiling points of alkyl halides decrease in the order:
RI > RBr > RCl > RF
Reason: The boiling points of alkyl chlorides, bromides and iodides are considerably higher than that of the hydrocarbon of comparable molecular mass.
