Question

Which of the following below explain why the alcohol is used in excess in this reaction. Note that there may be more than one answer.

Excess alcohol completely neutralizes the sulfuric acid and makes the reaction safer. The alcohol is used in excess to remove all of the protons from the carboxylic acid. This is a reversible reaction and adding excess alcohol drives the reaction towards the products. There is no need to add excess alcohol, excess ester should be added. The alcohol is less expensive and easier to remove from the product mixture than the carboxylic acid, but an excess of either would help in this reaction. This is a reversible reaction and adding excess alcohol drives the reaction towards the reactants. The alcohol is used in excess to make the reaction mixture soluble in ether during the extraction phase.
