question_answer 62)

  Which is the correct increasing order of boiling points of the following compounds ? 1-Iodobutane, 1-Bromobutane, 1-Chlorobutane, Butane (a) Butane < 1-Chlorobutane < 1-Bromobutane < 1-Iodobutant (b) 1-Iodobutane < 1-Bromobutane < 1-Chlorobutane < Butane (c) Butane < 1-Iodobutane < 1-Bromobutane < 1-Chlorobutail (d)  Butane < 1-Chlorobutane < 1-Iodobutane < 1-Bromobutan

Answer:

  (a) For the same alkyl halide, boiling points increase as the mass of the halogen increases. Thus, option (d) is correct.
