Haloalkanes and Haloarenes
Question
Wired Faculty App

Arrange each set of compounds in order of increasing boiling points:
Bromomethane, Bromoform, Chloro-methane, Dibromomethane.

Answer

Alkyl halides containing same alkyl group,the boiling point increases with an increase in the atomic mass of the halgoen. Since the atomic mass bromine is greater than chlorine, the boiling point of bromomethane is higher than that of chloromethane. Also, for alkyl halides containing the same alkyl group, the boiling point inrease in as number of halide group increase. Therefore, the boiling point of dibromomethane is higher than chloromethane and bromomethane, but lower than bromoform. Such as,
Chloromethane<bromomethane<dibromomethane<bromoform.
