Comparing the enthalpy changes of combustion of different alcohols Altaf Korimbocus Aim I am going to investigate the difference in enthalpy of combustion for a number of alcohols, the enthalpy of combustion being the 'enthalpy change when one mole of any substance is completely burnt in oxygen under the stated conditions'. I plan to find out which alcohol, out of methanol, ethanol, propanol and butanol, produces the most energy when burned in air Background and other information Methanol is the smallest alcohol, it releases 524.5 kJ mol-1, the next largest, Ethanol is one carbon and two hydrogen's larger, It release 1013 kJ mol-1 this is a difference of 488.5 kJ mol-1 this trend continues as the alcohols get larger. This is effectively because the only difference between the alcohols is a increase in size by one carbon and two hydrogen's each time. For my investigation I am going to use propan-1-ol and butan-1-ol as representatives of...
