Current Question (ID: 8086)

Question:

The specie with the shortest bond length is:

Options:

1. $\text{O}_2^+$
2. $\text{O}_2^-$
3. $\text{O}_2^{2-}$
4. $\text{O}_2^{2+}$ (Correct)

Solution:

HINT: Bond order $\propto \frac{1}{\text{Bond length}}$ Explanation: The bond order relation with bond length is as follows: Bond order $\propto \frac{1}{\text{Bond length}}$ Bond orders of $\text{O}_2^+$, $\text{O}_2^-$, $\text{O}_2^{2-}$ and $\text{O}_2^{2+}$ are respectively $2.5$, $1.5$, $1$ and $3$. Hence $\text{O}_2^{2+}$ is the shortest in bond length because it has the highest bond order.
