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 Trans-Esterification:**
Trans-esterification is a chemical process where an ester reacts with an alcohol to form a different ester and a different alcohol. This process involves the exchange of the organic groups (R groups) between the alcohol and the ester.

2. **Identifying the Reaction:**
The general reaction can be represented as:
\[ R_1COOR_2 + R_3OH \rightarrow R_1COOR_3 + R_2OH \]
Here, \( R_1COOR_2 \) is the starting ester, \( R_3OH \) is the alcohol, and the products are a new ester \( R_1COOR_3 \) and a new alcohol \( R_2OH \).

3. **Catalysis:**
The reaction can be catalyzed by either an acid or a base. This means that the presence of an acid or base can speed up the reaction without being consumed in the process.

4. **Products of Trans-Esterification:**
The products of trans-esterification are:
- A new ester (formed from the original ester and the alcohol)
- A new alcohol (formed from the original alcohol and the ester)

5. **Evaluating Statements:**
Now, let's evaluate the provided statements:
- **Statement 1:** Conversion of aliphatic acid to ester. (Incorrect)
- **Statement 2:** Conversion of aromatic acid to ester. (Incorrect)
- **Statement 3:** Conversion of one ester to another ester. (Correct)
- **Statement 4:** Conversion of ester into components namely acid and alcohol. (Incorrect)

The correct statement regarding trans-esterification is the conversion of one ester to another ester.

6. **Conclusion:**
Therefore, trans-esterification is the process of exchanging the organic groups between an ester and an alcohol, resulting in the formation of a new ester and a new alcohol.

**Final Answer:**
Trans-esterification is the process of converting one ester into another ester.
