Question 2

During saponification, which reagent is required to cleave the ester bonds in a triglyceride?

Accepted Answer

NaOH

Question 3

What is the main difference between acid-catalyzed hydrolysis and saponification of triglycerides?

Accepted Answer

Saponification produces fatty acid salts, while acid hydrolysis produces free fatty acids.

Question 7

Which of the following is a correct description of the role of NaOH in saponification?

Accepted Answer

It acts as a base to break ester bonds and form fatty acid salts.

Question 8

Which of the following is the correct name for the salt produced when myristic acid undergoes saponification with KOH?
