JEE Advanced Chemistry question

Not in JEE Main or NEET syllabus

Alkali ozonides are

(A)Paramagnetic in nature
(B)Hydrolytically unstable and decompose to superoxides
(C)Decreasing in stability as size of alkali metal decreases
(D)Having all the above statements as correctCorrect

Answer: (D)

Solution

The ozonide ion, O3⁻, carries an unpaired electron, making alkali-metal ozonides (MO3) paramagnetic, confirming (a). These salts are also thermally/hydrolytically unstable, decomposing with loss of oxygen toward the related superoxide, confirming (b). Larger alkali-metal
