Give explanation of following :
(i) During the preparation of esters from a carboxylic acid and an alcohol in the easter should be removed as soon as it is formed.

Explanation

**Step-by-Step Solution:**

1. **Understanding Esterification**: Esterification is a chemical reaction that occurs between a carboxylic acid and an alcohol to form an ester and water. The general reaction can be represented as:
\[ \text{Carboxylic Acid} + \text{Alcohol} \rightleftharpoons \text{Ester} + \text{Water} \]

2. **Example Reaction**: For instance, acetic acid (CH₃COOH) reacts with ethanol (C₂H₅OH) to produce ethyl acetate (CH₃COOC₂H₅) and water (H₂O):
