In the reaction sequence,

{\mathrm{C}_2}{\mathrm{H}_5}\mathrm{Cl\;} + \mathrm{\;KCN}\xrightarrow{{{\mathrm{C}_2}{\mathrm{H}_5}\mathrm{OH\;}}}\;X\xrightarrow[\Delta ]{{{\mathrm{C}_2}{\mathrm{H}_5}\mathrm{OH\;}}}Y

What is the molecular formula of Y?

View answer and explanation

Correct option: A

{\mathrm{C}_3}{\mathrm{H}_6}{\mathrm{O}_2}

Option A (

{\mathrm{C}_3}{\mathrm{H}_6}{\mathrm{O}_2}

) is correct because the reaction sequence leads to the formation of propanoic acid.
