Investigation and Preparation of Esterification Lab Introduction Esters are classified as organic compounds commonly derived from carboxylic acids. They are compounded from the reaction of a carboxylic acid with an alcohol in the presence of a strong acid to be used as a catalyst. The formula that represents an ester is R-COO-R where both Rs’ are alkyl groups‚ one which is bonded to an oxygen‚ and the other to a carbon which is double bonded to 1 oxygen and single bonded to the other.

that molecule than the other alcohols. Within a molecule there are bond energies that are holding the atoms together. When the fuel combusts a chemical reaction takes place‚ this breaks the bonds‚ this requires energy‚ and makes new bonds this gives out energy. The energy differences between the two tell us how much energy was given out or taken in. We can show this on a graph. ENERGY CHANGES DURING A REACTION To find the bond energies in the molecule of the alcohol we have to look at the how
