How will you carry out the following conversion : Acetic acid to propionic acid ?

Explanation

To convert acetic acid (CH₃COOH) to propionic acid (CH₃CH₂COOH), we can follow these steps:

### Step 1: Convert Acetic Acid to Ethanol
- **Reaction**: Use Lithium Aluminium Hydride (LiAlH₄) to reduce acetic acid to ethanol (CH₃CH₂OH).
- **Equation**:
\[ \text{CH}_3\text{COOH} \xrightarrow{\text{LiAlH}_4} \text{CH}_3\text{CH}_2\text{OH} \]
