Question

Find the number of moles of glycerol produced when \( n \) mole of triglyceride undergoes saponification.

• A. \( n \)
• B. \( 2n \)
• C. \( 3n \)
• D. \( \frac{3}{2}n \)

Hint:

1 Triglyceride $\rightarrow$ 1 Glycerol + 3 Fatty acid salts (Soap).

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
Saponification is the alkaline hydrolysis of fats or oils (triglycerides) to produce glycerol and soap.
Step 2: Key Formula or Approach:
Reaction:
1 Triglyceride + 3 NaOH \( \rightarrow \) 1 Glycerol + 3 Soap (Sodium salts of fatty acids).
Step 3: Detailed Explanation:
From the balanced chemical equation, the stoichiometric ratio between the triglyceride and glycerol is \( 1:1 \).
This means:
1 mole of triglyceride produces 1 mole of glycerol.
Therefore, \( n \) moles of triglyceride will produce \( n \) moles of glycerol.
Step 4: Final Answer:
The number of moles of glycerol produced is \( n \).
