Learning Check

Aspirin stored for a long time may undergo hydrolysis in the presence of water and heat. What will be the products of this reaction?

To write the hydrolysis products, separate the compound at the ester bond. Complete the formula of the carboxylic acid by adding –OH (from water) to the carbonyl group and –H (from water) to the alcohol.
