Reasoning It depends on number of electrons in the bonding and antibonding orbitals .

Options

A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1
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, Statement-2 is True.

Explanation

To solve the question, we need to analyze both the assertion and the reasoning provided.

### Step 1: Understanding the Assertion
The assertion states that "Bond order in a molecule can assume any integral value or fractional value including zero."

- **Bond Order Definition**: Bond order is defined as the difference between the number of bonding electrons and the number of antibonding electrons, divided by 2.

\[ \text{Bond Order} = \frac{(\text{Number of bonding electrons} - \text{Number of antibonding electrons})}{2} \]

### Step 2: Evaluating the Assertion
- The bond order can indeed take fractional values (like 1.5) and integral values (like 1, 2, etc.).
- However, the bond order cannot be negative or less than zero because the number of antibonding electrons cannot exceed the number of bonding electrons in a stable molecule.

Thus, the assertion is **false** because it incorrectly includes zero as a possible bond order.

### Step 3: Understanding the Reasoning
The reasoning states that "It depends on the number of electrons in the bonding and antibonding orbitals."

- This statement is true. The bond order is directly calculated based on the number of electrons in bonding and antibonding orbitals.

### Step 4: Evaluating the Reasoning
- Since the bond order is calculated using the formula mentioned, the reasoning is indeed correct. It accurately describes how bond order is determined.

### Conclusion
- The assertion is **false** because bond order cannot be zero or negative.
- The reasoning is **true** because it correctly explains the dependence of bond order on the number of bonding and antibonding electrons.

### Final Answer
- The assertion is false, and the reasoning is true. Therefore, the correct option is that the assertion is false, and the reasoning is true.
