Question

When $N_2$ goes to $N_2^{+}$, the $N-N$ bond distance increase, and when $O_2$ goes to $O_2^{+}$, the $O-O$ bond distance decrease.

Write the above statement is true or false:

Answer 1

When $N_2$ goes to $N_2^{+}$, the $N-N$ bond distance increase, and when $O_2$ goes to $O_2^{+}$, the $O-O$ bond distance decrease.

The bond order of the nitrogen molecule is $3$. An electron from bonding pi MO is lost to form $N_2^{+}$. The bond order decreases to $2.5$.
This decreases the strength of the bond and the bond distance increase.

The bond order of oxygen is $2$. An electron is lost from antibonding pi MO to form $O_2^{+}$. The bond order increases to $2.5$. This increases the strength of the bond and the bond distance decreases.

So, the correct statement is true.
