The correct statement(s) about O3 is (are)


A) O-O bond lengths are equal

B) thermal decomposition of $O_{3}$ is endothermic

C) $O_{3}$ is diamagnetic in nature

D) $O_{3}$ has a bent structure

Answer:

Option A,C,D

Explanation:

Plan Due to resonance, bond lengths between two atoms are equal. Species is said to be diamagnetic  if all electrons are paired process is endothermic if it takes place with the absorption of heat

 bent molecule

 all electrons paired thus, diamagnetic  

 2O3  → 3O2 , $\triangle $ H° = -142 kJ mol-1

                     Exothermic

 Thus, (b)  is incorrect

 (a,c, d ) are correct
