Vedclass · Answer

(C) The electron affinity of halogens generally increases as we move up the group from $I$ to $F$ due to the decrease in atomic size.However,$F$ has an exceptionally low electron affinity compared to $Cl$ due to its small size,which leads to strong inter-electronic repulsions between the incoming electron and the existing electrons in the $2p$ subshell.Therefore,the correct order of electron affinity for halogens is $Cl > F > Br > I$.Comparing the given options,$Br < Cl$ is correct.

Which of the following is correct for the electron affinity of halogens?
