the final product (C) is:

Options

A. Ammonium acetate
B. Acetamide
C. Amino methane
D. Ethanal

Answer

To solve the problem step by step, we will analyze the reactions involved and identify the final product (C) in the given sequence of reactions.

### Step 1: Reaction of Acetic Acid with PCl5
- **Starting Compound**: Acetic Acid (CH₃COOH)
- **Reagent**: PCl₅
- **Reaction**: PCl₅ reacts with the hydroxyl (OH) group in acetic acid, replacing it with a chlorine (Cl) atom.

**Product A**: The product formed is Acetyl Chloride (CH₃COCl).

### Step 2: Reaction of Acetyl Chloride with Ammonia
- **Starting Compound**: Acetyl Chloride (CH₃COCl)
- **Reagent**: Ammonia (NH₃)
- **Reaction**: Ammonia acts as a nucleophile and attacks the electrophilic carbon of the carbonyl group in acetyl chloride. This leads to the formation of an intermediate that eventually loses HCl.

**Product B**: The product formed is Acetamide (CH₃CONH₂).

### Step 3: Reaction of Acetamide with NaBrO
- **Starting Compound**: Acetamide (CH₃CONH₂)
- **Reagent**: Sodium Bromate (NaBrO)
- **Reaction**: This reaction is a classic example of the Hofmann degradation reaction. The amide reacts with NaBrO, where the nitrogen's hydrogen is abstracted, leading to the formation of a bromamide intermediate. This intermediate undergoes rearrangement and elimination to form a primary amine.

**Product C**: The final product formed is Methylamine (CH₃NH₂).

### Final Answer
The final product (C) is **Methylamine (CH₃NH₂)**.
