NEET levelSingle correct optionDifficulty 1 of 3hc129

Ethene is treated with $O X_{3}$ and the ozonide is then decomposed with $Zn$ / $H X_{2} O$ . The product is

Amethanoic acid
Bethane-1,2-diol
Cethanal
Dmethanal (2 mol per mol of ethene)

Answer: D

Ozonolysis cleaves the

C = C

bond and each

= CH X_{2}

end becomes

HCHO

. The reductive work-up stops at the aldehyde, so two moles of methanal result.
