MCQ
Which of the following has the minimum bond length ?
- A$O_2^+$
- B$O_2^-$
- ✓$O_2^{2-}$
- D$O_2$
✓
Answer
Correct option: C.
$O_2^{2-}$
c
Bond order of $O_{2}^{+}=\frac{10-5}{2}=2.5$
Bond order of $O_{2}^{+}=\frac{10-5}{2}=2.5$
Bond order of $O_{2}=\frac{10-7}{2}=1.5$
Bond order of $O_{2}^{2-}=\frac{10-8}{2}=1$
Bond order of $O_{2}=\frac{10-6}{2}=2$
Maximum bond order $=$ minimum bond length.
Bond length is minimum for $O_{2}^{+}$
