The correct statement(s) about O3 is/are

Question

The correct statement(s) about O3 is/are (A) O-O bond lengths are equal (B) thermal decomposition of O3 is endothermic (C) O3 is diamagnetic in nature (D) O3 has a bent structure

Process is endothermic if it takes place with absorption of heat. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/7f3c684cdd9ae8aa0e17c3208507df98-.png" /> bent molecule all electrons paired thus, diamagnetic 2 O 3 longrightarrow 3 O 2 Δ H°=-142 kJ mol -1 Exothermic Thus, (b) is incorrect. (a, c, d) are correct.

Q. The correct statement(s) about $O_{3}$ is/are

$O - O$ bond lengths are equal

thermal decomposition of $O_{3}$ is endothermic

$O_{3}$ is diamagnetic in nature

$O_{3}$ has a bent structure

Process is endothermic if it takes place with absorption of heat.

bent molecule all electrons paired thus, diamagnetic
$2 O_{3} ⟶ 3 O_{2}$
$Δ H^{\circ} = - 142 k J m o l^{- 1}$
Exothermic
Thus, (b) is incorrect. (a, c, d) are correct.
