Which is the correct increasing order of boiling points of the following compounds-
1-bromoethane, 1-bromopropane, 1-bromobutane, bromobenzene.

Options

A. bromobenzene lt 1-bromobutane lt 1-bromopropane lt 1-bromoethane
B. bromobenzene lt 1-bromoethane lt 1-bromopropane lt 1-bromobutane
C. 1-bromopropane lt 1-bromobutane lt 1-bromoethane lt bromobenzene
D. 1-bromoethane lt 1-bromopropane lt 1-bromobutane lt bromobenzene

Answer

D

Explanation

Hint: For alkyl or aryl halides containing the same halogen atom, boiling point increases as the mass of the hydrocarbon part increases.
