Question

An element ' $E^{\prime}$ has the ionisation enthalpy value of $374 \mathrm{~kJ} \mathrm{~mol}^{-1}$. ' $E$ ' reacts with elements $\mathrm{A}, \mathrm{B}, \mathrm{C}$ and D with electron gain enthalpy values of $-328,-349,-325$ and $-295 \mathrm{~kJ} \mathrm{~mol}^{-1}$, respectively. The correct order of the products EA, EB, EC and ED in terms of ionic character is :

Aicharya · Accepted Answer

The element having high value of Electron gain enthalpy (magnitude) will form a compound having higher ionic character so order of ionic character $E B>E A>E C>E D$

An element ' \(E^{\prime}\) has the ionisation enthalpy value of \(374 \mathrm{~kJ} \mathrm{~mol}^{-1}\). '…
