(A) The ionic character of a bond is related to the electronegativity difference between the bonded atoms. In the formation of an ionic bond between $E$ and a non-metal,the ionic character increases as the electron gain enthalpy of the non-metal becomes more negative (i.e.,the non-metal becomes more electronegative). Given electron gain enthalpy values: $B (-349 \ kJ \ mol^{-1}) Since $B$ has the most negative electron gain enthalpy,it is the most electronegative,resulting in the highest ionic character for $EB$. Thus,the order of ionic character is $EB > EA > EC > ED$.

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