Acetamide changes into methylamine by

Options

A. Hofmann bromamide reaction
B. Hofmann rection
C. Friedel- Craft's reaction
D. Hinsberg reaction

Explanation

To convert acetamide (CH3CONH2) into methylamine (CH3NH2), we can follow these steps:

### Step 1: Identify the Reactants and Products
- **Reactant**: Acetamide (CH3CONH2)
- **Product**: Methylamine (CH3NH2)

### Step 2: Understand the Reaction Type
The transformation from acetamide to methylamine involves the removal of the carbonyl group (C=O) from acetamide. This is typically achieved through a reduction reaction.

### Step 3: Choose the Appropriate Reagent
To achieve this reduction, we can use Bromine (Br2) in the presence of a strong base (alkali), which is part of the Hofmann degradation reaction. The specific reagent combination is Br2 and NaOH (sodium hydroxide).

### Step 4: Write the Reaction
The reaction can be summarized as follows:
1. Acetamide reacts with Br2 and NaOH.
2. The carbonyl group is removed, resulting in the formation of methylamine.

The reaction can be represented as:
\[ \text{CH}_3\text{CO}\text{NH}_2 + \text{Br}_2 + \text{NaOH} \rightarrow \text{CH}_3\text{NH}_2 + \text{by-products} \]

### Step 5: Conclusion
Thus, acetamide can be converted into methylamine using the Hofmann degradation reaction with Br2 and alkali.
