\mathrm{CH}

≡

\mathrm{CH}\xrightarrow{{{\mathrm{O}_3}/\mathrm{NaOH}}}X\xrightarrow{{\mathrm{Zn}/\mathrm{C}{\mathrm{H}_3}\mathrm{COOH}}}Y

is:

View answer and explanation

Correct option: A

\mathrm{C}{\mathrm{H}_2}\mathrm{OH}

—

\mathrm{C}{\mathrm{H}_2}\mathrm{OH}

Option A (

{\mathrm{CH}_2}\mathrm{OH}

—

{\mathrm{CH}_2}\mathrm{OH}

) is correct because the reaction sequence involves oxidative cleavage of alkyne to glyoxal followed by reduction to ethylene glycol.
