1-Iodobutane, 1-Bromobutane, 1-Chlorobutane, Butane

• A. Butane < 1-Chlorobutane < 1-Bromobutane < 1-Iodobutane
• B. 1-Iodobutane < 1-Bromobutane < 1-Chlorobutane < Butane
• C. Butane < 1-Iodobutane < 1-Bromobutane < 1-Chlorobutane
• D. Butane < 1-Chlorobutane < 1-Iodobutane < 1-Bromobutane

Answer 1

Answer: (A)

For the same alkyl halide, boiling point increases as the mass of halogen increases.
