    since they belong to the same homologous series,that means they are both alkanol,thus no.of carbon atoms in the compound depends the energy required to undergo complete combustion.so boiling pt of butan-1-ol is higher than that of ethanol.

    enthalpy of combustion meaning that the energy change of 1 mole of reactant to undergo complete combustion.
