Question

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:

(A) EA > EB > EC > ED
(B) ED > EC > EB > EA
(C) EB > EA > EC > ED
(D) ED > EC > EA > EB

Correct answer: A. E is metal and A, B, C & D are non-metal. For non metals as Heg becomes more negative more metallic character also increases.
