Question

The reaction between sodium hydroxide and ester of fatty acid is

• A. Esterification
• B. Pyrophosphorolysis
• C. Saponification
• D. Neutralization reaction

Hint:

Saponification = Base hydrolysis of esters → Produces soap Used in soap manufacturing.

Answer 1

The Correct Option is C

Concept: The reaction of an ester (especially of fatty acids) with a strong base like sodium hydroxide results in the formation of soap and alcohol. This process is known as saponification.

Step 1: Understand the reaction.
\[ \text{Ester} + NaOH \rightarrow \text{Soap} + \text{Alcohol} \]

Step 2: Identify the process.
This alkaline hydrolysis of esters is specifically called saponification.

Step 3: Analyze other options.

• Esterification → Formation of ester (opposite reaction)
• Pyrophosphorolysis → Not related
• Neutralization → Acid + base reaction (not applicable here)

Step 4: Final conclusion.
Thus, the reaction is: \[ Saponification \]
