B. Statement -1 is True, Statement -2 is True, Statement-2 is NOT a correct explanation for Statement -1
C. Statement -1 is True, Statement -2 is False
D. Statement -1 is False, Statmenet -2 is True

Answer

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

**Statement 1:** Equivalent weight of an acid is always less than its molecular weight.
**Statement 2:** Equivalent weight of acid = (Molecular weight) / (n-factor).

### Step-by-Step Solution:

1. **Understanding Equivalent Weight:**
- The equivalent weight of an acid is defined as the mass of the acid that can donate one mole of hydrogen ions (H⁺) in a reaction.
- The formula for calculating equivalent weight is:
\[ \text{Equivalent Weight} = \frac{\text{Molecular Weight}}{\text{n-factor}} \]

2. **Analyzing Statement 2:**
- Statement 2 states that the equivalent weight of an acid is given by the formula above.
- This formula is indeed correct, as it accurately describes how to calculate the equivalent weight based on the molecular weight and the n-factor of the acid.

3. **Understanding n-factor:**
- The n-factor for an acid is the number of H⁺ ions that can be replaced or donated by one molecule of the acid.
- For example, in hydrochloric acid (HCl), the n-factor is 1 because it can donate one H⁺ ion.

4. **Analyzing Statement 1:**
- According to Statement 1, the equivalent weight of an acid is always less than its molecular weight.
- However, if the n-factor is 1 (as in the case of HCl), the equivalent weight will be equal to the molecular weight:
\[ \text{Equivalent Weight} = \frac{\text{Molecular Weight}}{1} = \text{Molecular Weight} \]
- Therefore, Statement 1 is not always true. It is only true when the n-factor is greater than 1.

5. **Conclusion:**
- Since Statement 1 is false (as it is not always less than the molecular weight), and Statement 2 is true, we conclude:
- **Statement 1 is False**
- **Statement 2 is True**

### Final Answer:
- **Statement 1 is False; Statement 2 is True.**
