Chemistry Coursework Introduction In this experiment our aim is to find out if the number of carbon atoms or bonds affects the energy output of 4 different alcohols when they are ignited. To investigate this we will use 4 different alcohols (Ethanol, Methanol, Propanol and Butanol) in an experiment in which we will ignite each of the 4 alcohols measuring the energy given off with a calorimeter. The 4 alcohols have a different number of carbon atoms in each molecule so any patterns or trends will tell us that the number of carbon atoms does affect the engery given off. Prediction An accurate prediction can be made by using bond energy tables because of the fact that our experiment is based on the number of bonds in a molecule. If these calculations produce a negative number then we know that energy has been realesed through the reaction and that it is...
