A: In Hofmann's bromamide degradation amines formed containing one carbon atom less than carbon atoms present in amide.
R: This reaction occurs through the formation of nitrine intermediate

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4)

Answer

To solve the assertion and reason question regarding Hofmann's bromamide degradation, we can break down the explanation into a step-by-step analysis.

### Step-by-Step Solution:

1. **Understanding Hofmann's Bromamide Degradation**:
- The reaction involves the conversion of an amide into an amine with the loss of one carbon atom.
- The general reaction can be represented as:
\[ RCONH_2 \xrightarrow{Br_2, NaOH} RNH_2 + CO_2 \]
- Here, \(RCONH_2\) is the amide, and \(RNH_2\) is the amine produced.

2. **Assertion Analysis**:
- The assertion states that in Hofmann's bromamide degradation, the amines formed contain one carbon atom less than the carbon atoms present in the amide.
- This is true because the reaction results in the formation of an amine (RNH2) and carbon dioxide (CO2), effectively removing one carbon atom from the original amide.

3. **Reason Analysis**:
- The reason states that this reaction occurs through the formation of a nitrene intermediate.
- This is false. The mechanism of Hofmann's bromamide degradation does not involve the formation of a nitrene. Instead, it involves the formation of an isocyanate intermediate.

4. **Conclusion**:
- Since the assertion is true and the reason is false, the correct relationship is that the assertion is true, but the reason is not a correct explanation of the assertion.

### Final Answer:
- **Assertion (A)**: True
- **Reason (R)**: False
- Therefore, the correct answer is that the assertion is true, and the reason is false.
