Question

The bond length the species `O_(2), O_(2)^(+) and O_(2)^(-)` are in the order of
A. `O_(2)^(+) gt O_(2) gt O_(2)^(-)`
B. `O_(2)^(+) gt O_(2)^(-) gt O_(2)`
C. `O_(2) gt O_(2)^(+) gt O_(2)^(-)`
D. `O_(2)^(-) gt O_(2) gt O_(2)^(+)`

Answer 1

Correct Answer - D
`O_(2)^(-) gt O_(2) gt O_(2)^(+)`
Lesser the bond order, more will be the bond length.
`B.O. : O_(2)^(-) (1.5),O_(2)(2.0),O_(2)^(+) (2.5).`
