The bond length in O2^+, O2, O2^- and O...

The bond length in `O_2^+, O_2, O_2^-` and ` O_2^(2-)` follows the order :

A

`O_2 gt O_2^(+) gt O_2^(2-) gt O_2^(-)`

B

`O_2^(-) gt O_2^(2-) gt O_2^(+) gt O_2`

C

`O_2^(+) gt O_2 gt O_2^(-) gt O_2^(2-)`

D

`O_2^(2-) gt O_2^(-) gt O_2 gt O_2^(+)`

Text Solution

Verified by Experts

The correct Answer is:
C

Thermal stability is directly proportional to bond order
B.O. of `O_2^(+) = 2.5` B.O. of `O_2` = 2
B.O. of `O_2^(-) = 1.5` B. O. of `O_2^(2-) = 1.0`
