A : `H_(2)N-overset(O)overset(||)(C)-CH_(3)` can give iodoform reaction.
R : `Cl-overset(O)overset(||)(C)-CH_(3)` can also give iodoform reaction due to presence of `-COCH_(3)` group.

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 analyze the given statements about the iodoform reaction, we will break down the assertion and reason step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion:**
- The assertion states that `H2N-CO-CH3` (Acetamide) can give an iodoform reaction.
- The iodoform reaction typically requires a methyl ketone (R-CO-CH3) or a compound that can be oxidized to form a methyl ketone.

2. **Analyzing the Structure of Acetamide:**
- Acetamide has the structure `H2N-CO-CH3`.
- It contains a carbonyl group (C=O) and a methyl group (CH3) attached to the carbonyl carbon.
- However, acetamide itself does not have a methyl ketone structure directly; it is an amide.

3. **Conclusion on Assertion:**
- Since acetamide does not directly fit the criteria for the iodoform reaction (which requires a methyl ketone), the assertion is **false**.

4. **Understanding the Reason:**
- The reason states that `Cl-CO-CH3` (Chloroacetone) can also give an iodoform reaction due to the presence of the `-CO-CH3` group.
- Chloroacetone has the structure `Cl-CO-CH3`, which indeed contains a methyl ketone structure.

5. **Analyzing the Structure of Chloroacetone:**
- Chloroacetone has a carbonyl group (C=O) and a methyl group (CH3) attached to the carbonyl carbon.
- This structure fits the criteria for the iodoform reaction, as it can be oxidized to form a methyl ketone.

6. **Conclusion on Reason:**
- Since chloroacetone does fit the criteria for the iodoform reaction, the reason is **true**.

7. **Final Conclusion:**
- The assertion is false, and the reason is true. Therefore, the statement that the reason correctly explains the assertion is incorrect.

### Final Answer:
- Assertion: False
- Reason: True
- The reason does not correctly explain the assertion.
