An element ‘E’ has the 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 :

1. EB > EA > EC > ED
2. ED > EC > EA > EB
3. EA > EB > EC > ED
4. ED > EC > EB > EA

Correct answer: EB > EA > EC > ED
