Question

The necessary condition(s) for formation of ionic bond is/are:
(i) Low ionisation energy of electropositive element
(ii) Low ionisation energy of electronegative element
(iii) High electron affinity of electropositive element
(iv) High electron affinity of electronegative element

• A. (i), (ii)
• B. (iii), (iv)
• C. (i), (iv)
• D. (ii), (iii)

Answer 1

The correct option is C (i), (iv)

Low ionisation energy of electropositive element favours the formation of cation while high electron affinity for electronegative element favours formation of anion.
