Example Question #2 : Carbonyl Reactions

What is a product when propyl-butanoate undergoes saponification?

Possible Answers:

None of these

Propanoic acid



Butyl propanoate

Correct answer:



When naming esters, the root word in the name describes the carbon chain that carries the carbonyl. Saponification describes the breaking up of an ester. This yields an alcohol and a carboxylic acid. The chain with the carbonyl is butyl, so the carboxylic acid will be butanoic acid. That means the side with the alcohol will be propanol.
