JEE Advanced Chemistry question

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

(A)O − O bond length are equalCorrect
(B)Thermal decomposition of O3 is endothermic
(C)O3 is diamagnetic in natureCorrect
(D)O3 has a bent structureCorrect

Answer: (A),(C),(D)

Solution

Ozone's two resonance structures place the delocalised π system symmetrically, making both O–O bonds of equal length (bond order 1.5 each), confirming (a). All electrons in O3 are paired, so it is diamagnetic, confirming (c); and its central oxygen carries one lone pair, giving a bent (V-shaped,
