When it comes to group 17 elements being the substituents, the boiling point increases as we go down the group and thus the increasing order of boiling point is:

Chloromethane, Bromomethane, Dibromomethane, Bromoform

D Devendra Khairwa

It is known that boiling point increases with increase in molecular mass when the alkyl group is the same.

So the order of increasing boiling point is Chloromethane <  Bromomethane  <  Dibromomethane  <  Bromoform
