Assertion `H_(2),Li_(2),B_(2)` each has a bond order of 1 and hence are equally stable
Reasoning Stability of molecule//ion depends only on bond order .

Options

A. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`
B. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`
C. If `(A)` is correct but `(R )` is incorrect
D. If both `(A)` and `(R )` are incorrect

Explanation

To solve the question regarding the assertion and reasoning statements about the bond order and stability of the molecules H₂, Li₂, and B₂, we will analyze each statement step by step.

### Step 1: Understanding Bond Order
Bond order is defined as the number of chemical bonds between a pair of atoms. It can be calculated using the formula:
\[ \text{Bond Order} = \frac{(\text{Number of bonding electrons} - \text{Number of antibonding electrons})}{2} \]

### Step 2: Calculate Bond Order for H₂
- Hydrogen (H) has an atomic number of 1, meaning each H atom has 1 electron.
