Statement-I: If decimolal solution of sodium chloride boils at `101.2^(@)C`, then decimolal solution of calcium chloride will also boil at the same temperature.
Because
Statement-II: For same molal concentration of aqueous solutions of electrolytes, the elevation of boiling point may not be same.

Answer

To analyze the given statements, we need to evaluate the validity of both Statement-I and Statement-II based on the principles of colligative properties, specifically the elevation of boiling point.

### Step-by-Step Solution:

1. **Understanding the Statements**:
- **Statement-I**: If a decimolal solution of sodium chloride (NaCl) boils at 101.2°C, then a decimolal solution of calcium chloride (CaCl2) will also boil at the same temperature.
- **Statement-II**: For the same molal concentration of aqueous solutions of electrolytes, the elevation of boiling point may not be the same.

2. **Analyzing Statement-I**:
- Sodium chloride (NaCl) dissociates in solution into two ions: Na⁺ and Cl⁻. Therefore, its van't Hoff factor (i) is 2.
- Calcium chloride (CaCl2) dissociates into three ions: Ca²⁺ and 2Cl⁻. Thus, its van't Hoff factor (i) is 3.
- The elevation in boiling point (ΔTb) is given by the formula:
\[ \Delta T_b = i \cdot K_b \cdot m \]
where:
- \(i\) = van't Hoff factor
- \(K_b\) = ebullioscopic constant of the solvent
- \(m\) = molality of the solution

3. **Comparing the Elevation of Boiling Points**:
- For NaCl (i = 2):
\[ \Delta T_b = 2 \cdot K_b \cdot 0.1 \quad \text{(for decimolal solution)} \]
- For CaCl2 (i = 3):
\[ \Delta T_b = 3 \cdot K_b \cdot 0.1 \]
- Since the van't Hoff factors are different (2 for NaCl and 3 for CaCl2), the elevation of boiling points will also differ. Therefore, Statement-I is **false**.

4. **Analyzing Statement-II**:
- The statement claims that for the same molal concentration of aqueous solutions of electrolytes, the elevation of boiling point may not be the same.
- This is true because different electrolytes have different van't Hoff factors, which directly affect the boiling point elevation. Thus, Statement-II is **true**.

5. **Conclusion**:
- Statement-I is false, and Statement-II is true. Therefore, the overall conclusion is that the two statements are not consistent with each other.

### Final Answer:
- Statement-I: False
- Statement-II: True
