Investigating the energy released from burning different alcohols Alcohols burn and react with oxygen forming water and carbon dioxide; the equations below show the reactions between oxygen and 8 alcohols from methanol to ethanol. For these reactions to start, energy is required to break the existing bonds between the atoms of molecules of the reactants. For example in methanol, C-H bonds, C-O bond and O-H bonds and O=O double bonds need to be broken, energy is required to break these bonds as well as others in the reaction. However when new bonds are formed between atoms at the end of the reaction: C=O double bonds as well as O-H bonds are formed and as they are formed they release energy. As the energy released from the new bonds formed is more than the energy required to break the old bonds, the reaction is exothermic, overall it release energy into the surroundings....
