Question

$N_2$ and $O_2$ are converted to mono cations $N_2^{+}$ and $O_2^{+}$ respectively. The wrong statement with respect to given changes in the following is

• A. the N - N bond weakens
• B. the O - O bond order increases
• C. the $O-O$ bond length decreases
• D. $N_2^{+}$ becomes diamagnetic

Answer 1

Answer: (D)

B.O or $N_2=3$ and $N_2^{+}=2.5$



As here bond order decreases so $N-N$ bond get weak $N_2^{+}$ becomes paramagnetic

In case of $O_2$ and $O_2^{+}$

B.O or $O_2=2$ and $O_2^{+}=2.5$

as bond order increases so $O-O$ bond length decreases.
