Question

When hydrolyzed to its building blocks, a molecule of vegetable oil produces what compounds? In this experiment, when you mix methanol and sodium hydroxide together, the reaction below takes place CH_3OH + OH^- CH_3O^- + H_2O For this acid/base on the reactant side is _________ and the acid on the product side is _________. For CH_3OH, pKa = 15.5 and for H_2O, pKa = 15.7. Which is the stronger acid? Based on the pKa values given above, which is greater at equilibrium, reactant concentrations, or product concentrations? If, as is the case in this experiment, a large excess of CH_3 OH is used, the equilibrium will shift to (circle one: decrease the concentration of CH_3O, increase the concentration of CH_3O.)

Explanation / Answer

1. Vegetable oils consist of triglycerides. Triglycerides on hydrolysis produce diglycerides. Diglycerides on hydrolysis gives monoglyceride. Monoglyceride on hydrolysis produce glycerol.

So overall hydrolysis word equation is:-

Triglycerides+3H2O=glycerol+3 fatty acids.
