Boiling point (A) < Boiling point (B)
Boiling point (B) < Boiling point (C)
Dispersion forces only for (C)
Boiling point (B) > Boiling point (C)
Dispersion forces only for (B)
(C) exhibits hydrogen bonding
Boiling point (A) > Boiling point (B)

  1. This should get you started since both A and B are hydrocarbons. C is an alcohol and will exhibit hydrogen bonding; therefore, it will boil higher than either A or C.
