Vedclass · Answer

(C) In a period,the first ionization enthalpy generally increases from left to right. However,$N$ $(2s^2 2p^3)$ has a stable half-filled $p$-orbital configuration compared to $O$ $(2s^2 2p^4)$.Due to this stability,the ionization enthalpy of $N$ is higher than that of $O$.Therefore,the correct order for the first ionization enthalpy is $B Thus,the arrangement $B < C < N < O$ is incorrect.

In which of the following arrangements,the order is $NOT$ according to the property indicated against it?
