Explanation

To solve the question regarding the assertion and reason about the boiling and melting points of amides compared to corresponding acids, we will break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that the boiling and melting points of amides are higher than those of corresponding acids.
- To analyze this, we need to consider the structures of amides and acids.

2. **Structures of Amides and Acids**:
- Amides have the general structure: R-C(=O)-NH2 (where R is an alkyl group).
- Carboxylic acids have the structure: R-C(=O)-OH.
- Both functional groups contain a carbonyl group (C=O), but they differ in the presence of the nitrogen (N) in amides and the hydroxyl group (OH) in acids.

3. **Intermolecular Hydrogen Bonding**:
- Amides can form strong intermolecular hydrogen bonds due to the presence of the NH group.
- Carboxylic acids can also form hydrogen bonds due to the OH group.
- However, amides can engage in more extensive hydrogen bonding because they can form two hydrogen bonds per molecule (one from NH and one from the carbonyl oxygen).

4. **Electronegativity Considerations**:
- The electronegativity of oxygen is greater than that of nitrogen. This means that the hydrogen bonds in acids (which involve OH) may not be as strong as those in amides (which involve NH).
- The presence of two NH bonds in amides allows for stronger intermolecular forces compared to the single OH bond in acids.

5. **Conclusion on Boiling and Melting Points**:
- Due to the stronger intermolecular hydrogen bonding in amides, they require more energy to break these interactions, leading to higher boiling and melting points compared to corresponding acids.
- Therefore, the assertion is true.

6. **Understanding the Reason**:
- The reason states that the higher boiling and melting points of amides compared to acids are due to strong intermolecular hydrogen bonding in their molecules.
- This reason is also true as we have established that amides exhibit stronger intermolecular hydrogen bonding.

7. **Final Evaluation**:
- Both the assertion and reason are true, and the reason correctly explains the assertion.
- Thus, the correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

### Final Answer:
**Option A**: Both assertion and reason are true, and the reason is the correct explanation of the assertion.
