What is the purpose of using excess alcohol in a Fischer Esterification? 1) Using excess alcohol pushes the equilibrium reaction to the left, increasing the production of isopentyl acetate via Le Chatelier's principle. 2) Using excess alcohol pushes the equilibrium reaction to the right, decreasing the production of isopentyl acetate via Le Chatelier's principle. 3) Using excess alcohol pushes the equilibrium reaction to the left, decreasing the production of isopentyl acetate via Le Chatelier's principle. 4) Using excess alcohol pushes the equilibrium reaction to the right, increasing the production of isopentyl acetate via Le Chatelier's principle.
