Alcohols have varied uses in today's world, especially as fuels. Burning of alcohols produces water as well as energy which can be harnessed and used as biofuels. When used as biofuels, they are utilized in powering motor vehicles and in cooking (Wade 550-700). Ethanol is the most commonly used alcohol in the industrial level but recent studies have suggested that there are better options which are less corrosive and more efficient (Wade 550-700).. This mainly applies to branched alcohols but this paper will mainly look at straight chain alcohols for an easy and simplified analysis. This study would give an introductory phase for further studies. The paper delves into establishing a link between the energy output of various simple alcohols when they are subjected to heat and their structure. The study will precisely keep an eye on the numerical influence of carbon atoms forming the chain of homologous sequence of alcohols on the enthalpy variation of combustion. Hypothesis The initial phase of the hypothesis is that the enthalpy of combustion intensifies with the increase in the numerical quantities of carbon atoms. Variation in enthalpy comes about due to the variation in the energy levels needed for breaking the bonds in the alcohol chain and also from the energy released when forming new bonds. If the broken bonds are weaker than the newly-formed bonds, the released energy will be greater than the energy utilized (Wade 550-700).; as a result, this resultant energy will be released to the surroundings. This is the energy that can be harnessed and used as biofuels. Combustion of alcohols in the presence of oxygen results in the formation of carbon dioxide and water.
