An organic acid X is a liquid , which of ten freezes during winter time in cold countries having the molecular formula C_(2)H_(4)O_(2). On warming it with methanol in the presence of a few drops of concentrated suphuric acid, a compound Y with a sweet smell is formed. (a) Identify X and Y .Also write the formula showing the functional group present in them. (b) Write a chemical equation for the reaction involved.

1.	An organic acid X is a liquid , which of ten freezes during winter time in cold countries having the molecular formula C_(2)H_(4)O_(2). On warming it with methanol in the presence of a few drops of concentrated suphuric acid, a compound Y with a sweet smell is formed. (a) Identify X and Y .Also write the formula showing the functional group present in them. (b) Write a chemical equation for the reaction involved.
Answer» Solution :(i) X = Ethanoic acid `(CH_(3)COOH)` Y = Ethyl ethanoate `(CH_(3)COOC_(2)H_(5))` (ii) `underset("Ethanoic acid")(CH_(3)COOH)+underset("Ethanol")(C_(2)H_(5)OH) underset(Delta) overset("CONC. "H_(2)SO_(4))to underset("Ethyl ethanoate")(CH_(3)COOC_(2)H_(5))+H_(2)O`
