question_answer 63)

  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-Bromoethaii (b) Bromobenzene < 1-Bromoethane < 1-Bromopropane < 1-Bromobutane (c) 1-Bromopropane < 1-Bromobutane < 1-Bromoethane < Bromobutane (d)1-Bromoethane < 1-Bromopropane < 1-Bromobutane < Bromobenzene

Answer:

  (d) For the same halogen, boiling points increase as the size of the hydrocarbon part increases. Thus, option is correct.
