Question

In $O_2$ and $H_2{O}_2$, the $O-O$ bond lengths are $1.21$ and $1.48$ $\mathring{A}$ respectively. In ozone, the average $O-O$ bond length is:

• A. $1.28\mathring{A}$
• B. $1.18\mathring{A}$
• C. $1.44\mathring{A}$
• D. $1.52\mathring{A}$

Answer 1

The correct option is A $1.28\mathring{A}$

Ozone shows the given resonance structure.

It contains bond angle ${116.8}^o$ and $O-O$ bond length $1.28\mathring{A}$

So, the correct option is $A$
