Trans - esteritication is the process of

Options

A. Conversion of an aliphatic acid to ester
B. Conversion of an aromatic acid to ester
C. Conversion of one ester to another ester
D. Conversion of an ester into its components namely acid and alcohol

Answer

**Step-by-Step Solution:**

1. **Understanding Transesterification:**
Transesterification is a chemical process where one ester is converted into another ester. This typically involves the reaction of an ester with an alcohol.

2. **General Reaction:**
The general reaction can be represented as:
\[ R-C(O)-O-R' + R''OH \rightarrow R-C(O)-O-R'' + R'OH \]
Here, \( R-C(O)-O-R' \) is the starting ester, \( R''OH \) is the alcohol, and the products are a new ester \( R-C(O)-O-R'' \) and an alcohol \( R'OH \).

3. **Example of Transesterification:**
Consider the transesterification of triglycerides. A triglyceride can react with methanol:
\[ \text{Triglyceride} + 3 \text{Methanol} \rightarrow \text{Glycerol} + 3 \text{Esters} \]
This reaction illustrates how triglycerides (which are esters) can be converted into glycerol (an alcohol) and other esters.

4. **Analyzing the Options:**
- **Option 1:** Conversion of an aliphatic acid to ester - Incorrect.
- **Option 2:** Conversion of an aromatic acid to ester - Incorrect.
- **Option 3:** Conversion of one ester to another - Correct.
- **Option 4:** Conversion of an ester into its components (acid and alcohol) - Incorrect.

5. **Conclusion:**
Based on the analysis, the correct answer is that transesterification is the process of converting one ester to another ester.

**Final Answer:**
Transesterification is the process of conversion of one ester to another ester.
