The correct order in which the ` O-O` bond length increases in the following :

Options

A. `O_3 lt H_2O_2 lt O_2`
B. `O_2 lt O_3 lt H_2O_2`
C. `O_2 lt H_2O_2 lt O_3`
D. `H_2O_2 lt O_2 lt O_3`

Answer

C

Explanation

`O_2` is `overset(..)underset(..)O=overset(..)underset(..)O`, `H_2O_2` is `H-overset(..)underset(..)O-overset(..)underset(..)O-H`, and `O_3` has double bond character as it is a resonance hybrid:

Thus, the `O-O` bond length increases in the following order:
`O_2ltO_3ltH_2O_2`
