Vedclass · Answer

(B) The electronic configurations are: $C (2s^2 2p^2)$,$N (2s^2 2p^3)$,and $O (2s^2 2p^4)$.Nitrogen has a stable half-filled $2p$ subshell,which results in a higher ionization potential compared to both Carbon and Oxygen.Oxygen has a lower ionization potential than Nitrogen due to inter-electronic repulsion in the $2p^4$ configuration.Thus,the order of first ionization potential is $C  O > C$.Comparing this with the given options,option $B$ $(C  O)$ correctly represents the relative order where $N$ is the highest.
