10.6 Arrange each set of compounds in order of increasing boiling points.
(i) Bromomethane, Bromoform, Chloromethane, Dibromomethane.
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
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
