Molar Heat of Combustion of Alcohols Task: To find the molar heat of combustion of propanol, ethanol and butanol and to calculate the theoretical values using average bond enthalpies. Then to compare these to the practical values obtained from the experiments, also to predict the theoretical and practical molar heat of combustion of pentanol. Planning Background Information Alcohols: Alcohols are part of a family of compounds that are all based on a chain of carbon atoms. They can be considered derivatives of water in which the hydrocarbon atom has been replaced by a hydrocarbon chain. Alcohols all have the general formula CnH2n+1OH and which burn cleanly in oxygen or a plentiful supply of air to produce carbon dioxide and water vapour. If the air supply is reduced then they will burn to produce carbon monoxide, soot and water vapour. All Alcohols contain an oxygen atom in a hydroxyl group, meaning that the oxygen atom is joined to...
