The bond strength in O2+,O2,O2−\mathrm{O}_2^ + ,{\mathrm{O}_2},\mathrm{O}_2^ - and O22−\mathrm{O}_2^{2 - } follows the order:
View answer and explanation
Correct option: B
O2+>O2>O2−>O22−\mathrm{O}_2^ + > {\mathrm{O}_2} > \mathrm{O}_2^ - > \mathrm{O}_2^{2 - }
Option B (O2+>O2>O2−>O22−\mathrm{O}_2^ + > {\mathrm{O}_2} > \mathrm{O}_2^ - > \mathrm{O}_2^{2 - }) is correct because bond strength increases with bond order, and the bond orders are O2+ (2.5), O2 (2), O2- (1.5), and O22- (1).
