Each question contains STATEMENT-I(Assertion) and STATEMENT-2(Reason).the statement carefully and mark the correct answer according to the instruction given below:
STATEMENT - 1 : Elevation in boiling point will be high if the molal elevation constant of the liquid is high.
STATEMENT - 2 : Elevation in boiling point is a colligative property.

Options

A. If both the statements are TRUE and STATEMENT-2 is the correct explanation STATEMENT-1
B. If both the statements are TRUE but STATEMENT-2 is NOT the correct explanation STATEMENT-1
C. If STATEMENT-1 is TRUE and STATEMENT-2 is FALSE
D. If STATEMENT-1 is FALSE and STATEMENT-2 is TRUE

Answer

To solve the question, we need to analyze both statements provided:

**STATEMENT - 1:** Elevation in boiling point will be high if the molal elevation constant of the liquid is high.

**STATEMENT - 2:** Elevation in boiling point is a colligative property.

### Step-by-Step Solution:

1. **Understanding Elevation in Boiling Point:**
- The elevation in boiling point (ΔTB) is a phenomenon where the boiling point of a solvent increases when a solute is dissolved in it. This can be mathematically expressed using the formula:
\[ \Delta T_B = i \cdot K_B \cdot m \]
- Here, \(i\) is the Van't Hoff factor (which represents the number of particles the solute breaks into), \(K_B\) is the molal elevation constant of the solvent, and \(m\) is the molality of the solution.

2. **Analyzing STATEMENT - 1:**
- The first statement claims that if the molal elevation constant (\(K_B\)) is high, then the elevation in boiling point (\(ΔTB\)) will also be high.
- From the formula, we can see that \(ΔTB\) is directly proportional to \(K_B\). Therefore, if \(K_B\) increases, \(ΔTB\) will also increase, making STATEMENT - 1 true.

3. **Analyzing STATEMENT - 2:**
- The second statement states that elevation in boiling point is a colligative property.
- Colligative properties depend on the number of solute particles in a solution, not on the nature of the solute. Since elevation in boiling point is indeed a colligative property, STATEMENT - 2 is also true.

4. **Determining the Relationship Between the Statements:**
- While both statements are true, we need to determine if STATEMENT - 2 is the correct explanation for STATEMENT - 1.
- STATEMENT - 1 is about the effect of the molal elevation constant on the boiling point elevation, while STATEMENT - 2 describes the nature of elevation in boiling point as a colligative property. They are related but do not explain each other directly.

5. **Conclusion:**
- Since both statements are true but STATEMENT - 2 does not explain STATEMENT - 1, the correct answer is:
- **If both the statements are true, but statement 2 is not the correct explanation of statement 1.**

### Final Answer:
**Option B:** If both the statements are true, but statement 2 is not the correct explanation of statement 1.
