Monday 11th November 2002 Phillip Preston 11B Chemistry Coursework 'To investigate how the heat of combustion of alcohols varies with the number of carbon atoms in the alcohol' Plan The heat of combustion of any substance is the amount of heat energy given out when 1 mole of that substance burns completely in air. Every covalent bond has a 'bond energy', it is the amount of energy needed to break the bond or the amount of energy given out as a bond is formed. During this experiment I will be comparing the theoretical bond energies with that of the actual value gained during my experiment. To work this out I need the formulae of the alcohols I am going to be working with and the theoretical bond energies. These two tables show just that: Alcohol Formula Structure Methanol CH3OH Ethanol C2H5OH Propan-1-ol C3H7OH Butan-1-ol C4H9OH Pentan-1-ol C5H11OH Hexan-1-ol C6H13OH Bond Bond Energy/KJ C-C 347 C-H 413 C-O 336 C=O 805 O-H 464 O=O 497 I am going to investigate the amount of energy that alcohols give off when burnt. This will be caused by the...
