Properties of methanol, ethanol and propanol the alcohols methanol, ethanol and propanol all have the following properties [property: a chemical property is any characteristic that gives a substance the ability to undergo a change that results in a new substance they are colourless liquids that dissolve in water to form a neutral. The aim of this experiment is to investigate the effect that the number of carbons, in an alcohol, has on the enthalpy of combustion – and thereby the amount of energyreleased by the first five members of the alcohol homologous series. Alcohol combustion plan comparing the enthalpy changes of combustion of different alcohols aim in this experiment i will investigate the enthalpy changes of combustion in particular i will be investigating the enthalpy change of combustion for different alcohols i hope to investigate some of the homologous series alcohols, as well as a few structural isomers of these alcohols.

Enthalpy change combustion alcohol homologous series

(a) successive members of the homologous series of alcohols differ from each other by a -ch 2 group (b) the constant increase in the heat of combustion of the successive members of alcohol is due to the extra heat given out by the extra one carbon atom and two hydrogen atoms in the -ch 2 group when the heat of combustion is plotted against the number of carbon atoms per alcohol.
