NEET levelSingle correct optionDifficulty 1 of 3hc131

In the ozonolysis of alkenes, zinc dust is added in the work-up mainly to

Areduce the aldehydes to alcohols
Bact as a Lewis acid for the hydrolysis
Cdestroy the $H X_{2} O X_{2}$ formed, so that aldehydes are not oxidised to acids
Doxidise the ozonide to carboxylic acids

Answer: C

Hydrolysis of the ozonide produces

H X_{2} O X_{2}

, which would oxidise aldehydes to carboxylic acids. Zinc removes

H X_{2} O X_{2}

(and reduces peroxidic species), so carbonyl compounds are obtained as aldehydes or ketones.
