Question
Which of the following has the minimum bound length ?
Options
A.O2-
B.O22-
C.O2
D.O2+
Solution
Bond order of O2+ = 
= 2.5
Bond order of O2- =
= 2.5
Bond order of O22- =
= 2
Bond order of O2 =
= 2
∵ Maximum bond order = minimum bond length.
∴ Bond length is minimum for O2+
= 2.5 Bond order of O2- =
= 2.5Bond order of O22- =
= 2Bond order of O2 =
= 2∵ Maximum bond order = minimum bond length.
∴ Bond length is minimum for O2+
