The correct statement(s) about O 3 is(are)

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

Options

AO-O bond lengths are equal.
BThermal decomposition of O₃ is endothermic.
CO₃ is diamagnetic in nature.
DO₃ has a bent structure.

Correct answer

A. O-O bond lengths are equal.

Step-by-step solution

In ozone due to resonating structures O - O bond lengths are same

The correct statement(s) about O 3 is(are)

O-O bond lengths are equal is correct
$2 {\text{O}}_{3} ⟶ 3 {\text{O}}_{2} + 6 8 \text{Kcal}$
It is exothermic decomposition (O₃ unstable). Thermal decomposition of O₃ is endothermic is wrong
O₃ is diamagnetic in nature Is correct due to all paired electrons.
O₃ has a bent structure Is correct with a bond angle of 116.8^o and bent structure
