Vedclass · Answer

(B) Let us analyze each option: $1$. $Mn  Zn \, (IP)$: The first ionization potential $(IP)$ of $Cr$ $(3d^5 4s^1)$ is lower than $Mn$ $(3d^5 4s^2)$ due to the stability of the half-filled $d$-subshell in $Mn$. Thus,the order is incorrect. $2$. $La > Sc  Sc $3$. $F > P $4$. $Cl  Br \, (EA)$: The electron affinity $(EA)$ of $Cl$ is higher than $F$ due to inter-electronic repulsion in the small $2p$ orbital of $F$. Thus,$Cl > F$. The order is incorrect.
