Which of the following molecules have same bond order?
`{:(,H_(2),Cl_(2),CO,Br_(2),N_(2)),(,I,II,III,IV,V):}`

Options

A. I, II and IV have same bond order
B. III and V have same bond order
C. Both (a) and (b)
D. None of the above

Explanation

To determine which of the given molecules (H₂, Cl₂, CO, Br₂, N₂) have the same bond order, we will calculate the bond order for each molecule using the molecular orbital theory. The bond order can be calculated using the formula:

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

### Step 1: Calculate the bond order for H₂
- H₂ has 2 electrons.
