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-Bromobutane < 1-Bromoethane < Bromobenzene
• D. 1-Bromoethane < 1-Bromopropane < 1-Bromobutane < Bromobenzene

Answer 1

Answer: (D)

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