The reaction between an alcohol and an acid with the elimination of water molecule is called

Options

A. Esterification
B. Saponification
C. Etherification
D. Elimination

Answer

To solve the question regarding the reaction between an alcohol and an acid with the elimination of a water molecule, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are an alcohol (R'OH) and an acid (RCOOH).

2. **Understand the Reaction**:
- When an alcohol reacts with an acid, they undergo a chemical reaction where a water molecule (H2O) is eliminated.

3. **Write the Reaction**:
- The general reaction can be represented as:
\[ RCOOH + R'OH \rightarrow RCOOR' + H2O \]
- Here, RCOOR' is the product formed, which is an ester.

4. **Name the Reaction**:
- The process of forming an ester from an alcohol and an acid, with the elimination of water, is known as **esterification**.

5. **Conclusion**:
- Therefore, the answer to the question is that the reaction between an alcohol and an acid with the elimination of a water molecule is called **esterification**.
