Assertion (A) When methyl alcohol is added to water, boiling point of water increases.
Reason (R ) When a volatile solute is added to a volatile solvent evevation in boiling point is observed.

Options

A. Assertion and reason both are correct statements and reason is correcft explanation for assertion.
B. Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C. Assertion is correct statement but reason is wrong statement.
D. Assertion and reason both are incorrect statements.

Explanation

To solve the question regarding the assertion and reason provided, we will analyze both statements step by step.

### Step 1: Analyze the Assertion (A)
- **Assertion (A)**: "When methyl alcohol is added to water, the boiling point of water increases."
- **Analysis**: When a solute (in this case, methyl alcohol) is added to a solvent (water), it typically affects the boiling point of the solvent. However, methyl alcohol is a volatile solute. When a volatile solute is added to a solvent, it does not elevate the boiling point; instead, it can lower it due to the vapor pressure of the solute. Therefore, this assertion is **incorrect**.

### Step 2: Analyze the Reason (R)
- **Reason (R)**: "When a volatile solute is added to a volatile solvent, elevation in boiling point is observed."
- **Analysis**: The statement is misleading. When a volatile solute is added to a volatile solvent, the boiling point does not necessarily increase. In fact, the addition of a volatile solute can lead to a decrease in the boiling point of the solution due to the lowering of the solvent's vapor pressure. Therefore, this reason is also **incorrect**.

### Step 3: Conclusion
- Since both the assertion and the reason are incorrect, we conclude that the correct answer is that both the assertion and reason are false.

### Final Answer
Both Assertion (A) and Reason (R) are incorrect.
