Comparing the enthalpy changes of combustion of different alcohols. What are alcohols? Alcohol is the common family name for the hydrocarbon group alkanols. At least one of the hydrogen groups is replaced by an -OH group. They are all organic compounds. The general formulas for the alcohols are: CnH(2n+1)OH Where n represents a number. The first and simplest member of the alkanols family is methanol. Its molecular formula is CH3OH. You can now see that each member of the alcohol family has a different number of carbons in its structure. They increase by one carbon atom and two hydrogen atoms each time. The question that this piece of coursework is going to answer is "Is there a relationship between the number of carbon atoms in a chain and the enthalpy change of combustion?" Aim The aim of this experiment is to prove that the longer the hydrocarbon chain the higher the amount of energy transferred to the water, therefore fewer moles of...
