Which one of the following is an incorrect statement?

Options

A. a) O_(3)` oxidises PbS to Pb`SO_(4)`
B. b) O_(3)` oxidises nitric oxide to nitrogen dioxide
C. c) `O_(3)` oxidises aqueous Kl at pH=9.2
D. d) The two oxygen-oxygen bond lengths in `O_(3)` are different

Answer

D

Explanation

Ozone oxidises `PbS` to `PbSO (4) and NO` to `NO _(2).`
`Pb S (s) + 4 O _(3) (g) to Pb SO _(4) (s) + 4 O _(2) (g)`
`NO (g) + O _(3) (g) to NO _(2) (g) + O _(2) (g)`
It oxidises aqueous KI at pH 9.2 and acts as oxidising agent in the manufacture of `KMnO _(4).` It is a resonance hybrid of following two structures.

That.s why the two oxygen-oxgyen bond lengths in this molecule are identical.
