Question

Which is the correct increasing order of boiling points of the following compounds ?
1-bromoethane, 1-bromobutane, 1-bromopropane, 1-bromobenzene
A. Bromobenzene `lt` 1-Bromobutane `lt` 1-Bromopropane `lt` 1-Bromoethane
B. Bromopropane `lt` 1-bromoethane
`lt` 1-bromopropane `lt `1-romobutane.
C. 1-Bromopropane `lt` 1-Bromobutane `lt` 1-bromoethane `lt` Bromobenzene
D. 1-Bromoethane`lt` 1-bromopropane
`lt1-` bromobutane `lt` bromobenzene.

Answer 1

Correct Answer - D
It is the correct increasing order of boiling points. For the same halogen atom, boiling point increases with the increase in the size of alkyl group.
