$O < S < F < Cl$

Vedclass · Answer

(B) The correct order of electron gain enthalpy (with negative sign) is $O Generally,electron gain enthalpy becomes more negative (higher magnitude) across a period from left to right due to an increase in effective nuclear charge and a decrease in atomic size.Down a group,electron gain enthalpy becomes less negative due to an increase in atomic size.However,$F$ and $O$ have smaller sizes compared to $Cl$ and $S$ respectively,leading to strong inter-electronic repulsions in the $2p$ subshell. Consequently,$Cl$ has a higher electron gain enthalpy than $F$,and $S$ has a higher electron gain enthalpy than $O$.

Which one of the following arrangements represents the correct order of electron gain enthalpy (with negative sign) of the given atomic species :-
