An element ' E ' has the ionisation enthalpy value of $\displaystyle 374 \mathrm{~kJ} \mathrm{~mol}^{-1}$. ' E ' reacts with elements $\displaystyle \mathrm{A}, \mathrm{B}, \mathrm{C}$ and $\displaystyle D$ with electron gain enthalpy values of $\displaystyle -328,-349,-325$ and $\displaystyle -295 \mathrm{~kJ} \mathrm{~mol}^{-1}$, respectively. The correct order of the products EA, EB, EC and ED in terms of ionic character is :
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle \mathrm{EB}>\mathrm{EA}>\mathrm{EC}>\mathrm{ED}$
