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?
Solution
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.
