Question

Arrange each set of compounds, in the order of increasing boiling points.

(i) Bromomethane, Bromoform, Chloromethane, Dibromomethane

Answer 1

Since boiling points increase with increasing molecular mass due to the greater magnitude of Van der Waal's forces of attraction, the boiling points of these compounds increase in the order:

Chloromethane < bromomethane < dibromomethane < bromoform.
