Question

The correct statement(s) about $O_3$ is/are:

• A. $O-O$ bond lengths are equal
• B. Thermal decomposition of $O_3$ is exothermic
• C. $O_3$ is paramagnetic in nature
• D. $O_3$ has a bent structure

Answer 1

Answer: (A), (B), (D)

The correct options are
A $O-O$ bond lengths are equal
B Thermal decomposition of $O_3$ is exothermic
D $O_3$ has a bent structure

(a) Ozone molecule is resonance stabilized because of which all bond lengths are equal.


(b) Ozone decomposes to give oxygen molecules which are more stable than ozone molecules and hence the decomposition is exothermic.
(c) $O_3$ is diamagnetic in nature.
(d) It has a bent structure as shown above.
