The reaction between a glycerol molecule and three long-chain carboxylic acid molecules is a A - VCE - SSCE Chemistry - Question 2 - 2005 - Paper 1

In the context of glycerol reacting with long-chain carboxylic acids, the correct process to consider is hydrolysis. This reaction typically involves the breakdown of a compound by the addition of water, which is consistent with the formation of an ester group such as -C-O-C-.

During the hydrolysis of triglycerides (formed from glycerol and fatty acids), we generally end up with glycerol and fatty acids as products. Therefore, the option indicating a hydrolysis reaction leading to the presence of a -C-O-C- group is correct.
