Question: Increasing order of bond strength of O2, O2–, O22– and O2+ is:...
Increasing order of bond strength of O2, O2–, O22– and O2+ is:
A
O2+< O2< O2–< O22–
B
O2< O2+< O2–< O22–
C
O2–< O22–< O2+< O2
D
O22–< O2–< O2< O2+
Answer
O22–< O2–< O2< O2+
Explanation
Solution
O2 bond order = 2 ; O2– bond order = 1.5 ; O22– bond order = 1.0 ; O2+ bond order = 2.5.
