Bond order of `O_(2), O_(2)^(-), O_(2)^(+) and O_(2)^(2-)` is in order

A

`O_(2)^(-) lt O_(2)^(2-) lt O_(2) lt O_(2)^(+)`

B

`O_(2)^(2-) lt O_(2)^(-) lt O_2 lt O_(2)^(+)`

C

`O_(2)^(+) lt O_(2) lt O_(2)^(-) lt O_(2)^(2-)`

D

`O_(2) lt O_(2)^(+) lt O_(2)^(-) lt O_(2)^(2-)`

Text Solution

Verified by Experts

The correct Answer is:
B
`{:(O_(2), 16, 2.0),(O_(2)^(+), 15, 2.5), (O_(2)^(-),15, 1.5), (O_(2)^(2-),18,1.0):}`
Thus is in `O_(2)^(2-) lt O_(2)^(-) lt O-2 lt O_(2)^(+)`
