Vedclass · Answer

(D) The electronic configurations of the ions formed after the first ionization (removal of one electron) are:$C^+: 1s^2 2s^2 2p^1$$N^+: 1s^2 2s^2 2p^2$$O^+: 1s^2 2s^2 2p^3$$F^+: 1s^2 2s^2 2p^4$The second ionization enthalpy involves the removal of an electron from these species.$O^+$ has a stable half-filled $2p^3$ configuration,making the removal of the second electron most difficult.$C^+$ has a $2p^1$ configuration; removing this electron leads to a stable $2s^2$ configuration,making it relatively easier.Comparing the effective nuclear charge and stability,the order of second ionization enthalpy is $O > F > N > C$.
