Give steps involved in the conversion of :
Butan-1-ol to pent-2-enoic acid

Explanation

To convert butan-1-ol to pent-2-enoic acid, we will follow a series of chemical reactions. Here are the detailed steps involved in the conversion:

### Step 1: Conversion of Butan-1-ol to Butyl Bromide
- **Reaction**: Butan-1-ol (CH3-CH2-CH2-CH2-OH) reacts with hydrobromic acid (HBr).
- **Conditions**: Use concentrated sulfuric acid (H2SO4) as a catalyst.
- **Product**: Butyl bromide (CH3-CH2-CH2-CH2-Br) is formed through the substitution reaction.

### Step 2: Formation of Grignard Reagent
