Question

Which is the correct increasing order of boiling points of the following compounds.

1-Bromoethane , 1-Bromopropane, 1-Bromobutane,

Bromobenzene

• A. Bromobenzene < 1- Bromobutane < 1- Bromopropane < 1- Bromoethane
• B. Bromobenzene < 1- Bromoethane < 1- Bromopropane < 1- Bromobutane
• C. 1- Bromopropane < 1-bromobuatane < 1- Bromoehane < Bromobenzene
• D. 1- Bromoehane < 1- Bromopropane < 1- Bromobutane < Bromobenzene

Answer 1

Answer: (D)

1- Bromoehane < 1- Bromopropane < 1- Bromobutane < Bromobenzene

Answer 2

For the same halogen, boiling point increases as the size of the hydrocarbon part increases.
