question_answer 61)

    A compound X is formed by the reaction of a carboxylic acid  and an alcohol in the presence of a few drops of . The alcohol on oxidation with alkaline followed by acidification gives the same carboxylic acid as used in this reaction. Give the names and structures of carboxylic acid, (b) alcohol and (c) the compound X. Also write the reaction.

Answer:

                  (a) Carboxylic acid having molecular formula  is (acetic acid or ethanoic acid its structure is (b) Since, an alcohol which on oxidation with alkaline  followed by acidification gives ethanoic acid. Therefore, it must be ethanol. Its structure is (c) Since compound X is formed by the reaction of ethanoic acid with ethanol in presence of a few drops of cone. . Therefore, compound X must be an ester, i.e., ethyl ethanoate. Its structure is .The reaction is
