Question

Select the incorrect statement among the following.

• A. $O_3$ is used as germicide for purification of air
• B. In $O_3,O-O$ bond length is identical with that of molecular oxygen
• C. $O_3$ molecule is angular in shape
• D. $O_3$ is an oxidising agent

Answer 1

Answer: (B)

In $O_3,O-O$ bond length is identical with that of molecular oxygen

In $O_3,O-O$
bond length is not identical with that of the molecular oxygen. It is found to be intermediate of $O-O$ and $O=O$ bond lengths. This is due to resonance.
In ozone bond angle of $O-O-O$ is ${116.8}^{\circ }$ and bond length (O-O) is $1.278\stackrel{\circ }{A}$
