a compound X is formed by the reaction fo a carboxylic acid C₂H₄O₂and an alcohol in presence of a few drops of H₂SO₄.the alcohol on oxidation with alkaline KMnO₄followed by acidification gives the same carboxylic acid as used in this reacation . give the name and structures of the (a) carboxylic acid,(b)alcohol and (c) compound X.also write the reaction.

Solution

Mol. formula of acid = C₂H₄O₂
As it isan acid -COOH group has to be present, subtracting it from above formula we get = CH₃
Therefore the acid isCH₃COOH
The alcohol on oxidation is said to give the above acid, reducing it sequentially will give us ethanal and then, the alcohol ethanol = C₂H₅OH
CH₃COOH + C₂H₅OH -------> CH₃COOC₂H₅
Acetic Acid and alcohol will form ester ethyl acetate
