Vedclass · Answer

(B) The electron gain enthalpy is the energy released when an electron is added to a neutral gaseous atom. For the given elements,the values are: $N$: $+7 \ kJ/mol$ (positive due to stable half-filled $2p^3$ configuration) $O$: $-141 \ kJ/mol$ $Cl$: $-349 \ kJ/mol$ $Al$: $-43 \ kJ/mol$ Comparing the magnitudes,the order of electron gain enthalpy (most negative to least negative) is $Cl However,considering the standard convention where more negative values are considered 'higher' in terms of energy release,the order of increasing electron gain enthalpy is $Al < N < O < Cl$.

The correct order of electron gain enthalpy of $N$,$O$,$Cl$,$Al$ is
