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 - bromobutane < 1 - bromopropane < 1- bromobutane
(c) 1 - bromopropane < 1 - bromorpropane < 1 - bromoethane < Bromobenzene
(d) 1 - bromoethane < 1 - bromopropane < 1 - bromobutane < Bromobenzene

Answer 1

Since physical properties like the boiling point of hydrocarbons depend on its alkine group property. Hence the required series is (d).

Answer 2

CORRECT ANSWER IS:

(d) 1 - bromoethane < 1 - bromopropane < 1 - bromobutane < Bromobenzene
