MCQ
Which of the following pair is expected to have the same bond order?
- A$\text{O}_{2},\text{N}_{2}$
- ✓$\text{O}^{+}_{2},\text{N}^{-}_{2}$
- C$\text{O}^{-}_{2},\text{N}^{+}_{2}$
- D$\text{O}^{-}_{2},\text{N}^{-}_{2}$
✓
Answer
Correct option: B.
$\text{O}^{+}_{2},\text{N}^{-}_{2}$
Bonad order $=\frac{(\text{N}_{\text{b}}-\text{N}_{\text{a}})}{2}$
In $O_2$ number of electrons in bonding orbitita are $10$ and are $5.$
Bonad order $=\frac{(10-5)}{2}=2.5$
In $N_2$ number of electrons $10$ and are $3.$
In $O_2$ number of electrons in bonding orbitita are $10$ and are $5.$
Bonad order $=\frac{(10-5)}{2}=2.5$
In $N_2$ number of electrons $10$ and are $3.$
