Aim To find out difference in the heat of combustion for different types of alcohols. Hypothesis The higher the number of carbon atoms in an alcohol is‚ the higher the energy for the heat of combustion. Alcohol is a homologous series‚ a series of organic compounds with similar formula and chemical properties‚ and increase in molecular size and mass. When the equations for combustion of these alcohols are listed in the order of increasing number of carbon atoms‚ Methanol 1 CH3OH(l) + 3/2 O2(g)

Combustion Of Alcohols Planning This investigation involves burning alcohol in the air. Key science- Chemistry by Eileen Ramsden says that " an alcohol is a series of organic‚ homologous compounds‚ with the general formula Cn H2n+1OH". The alcohol reacts with the oxygen in the air to form the products water and carbon dioxide: Cn H2n+1OH +(n+n/2)-1O2 ? nH2O + nCO2 The structure of the molecules in this reaction is: H H | | H - C - C - O- H + 3[O=O] ? 1/2[O=C=O] + 3[H-O-H] | | H H This reaction
