To solve the question, we need to analyze the changes in bond distances when the molecules \(N_2\) and \(O_2\) are converted to their respective cations \(N_2^+\) and \(O_2^+\). ### Step-by-Step Solution: 1. **Understanding Bond Order**: - The bond order is a measure of the number of bonds between two atoms. It can be calculated using the formula: \[ \text{Bond Order} = \frac{(\text{Number of bonding electrons} - \text{Number of antibonding electrons})}{2} ...
