Distinguish between the following :
`MeCOCl` (ethanoyl chloride) and `(II) MeCOOH` (ethanoic acid)

Explanation

To distinguish between ethanoyl chloride (MeCOCl) and ethanoic acid (MeCOOH), we can analyze their chemical properties and reactions with specific reagents.

### Step 1: Chemical Structure
- **Ethanoyl Chloride (MeCOCl)**: This compound has the structure CH3C(=O)Cl. It is an acyl chloride, which means it contains a carbonyl group (C=O) attached to a chlorine atom.
- **Ethanoic Acid (MeCOOH)**: This compound has the structure CH3C(=O)OH. It is a carboxylic acid, which means it contains a carbonyl group (C=O) attached to a hydroxyl group (OH).

### Step 2: Reaction with Water
- **Ethanoyl Chloride**: When ethanoyl chloride is hydrolyzed in water, it reacts to form ethanoic acid and hydrochloric acid (HCl). The reaction can be represented as:
