Question

A carboxylic acid C₂H₄O₂ reacts with an alcohol in the presence of H₂SO₄ to form a compound 'X' . The alcohol on oxidation with alkaline KMnO₄, followed by acidification gives the same carboxylic acid, C₂H₄O₂. Write the name and structure of (a) carboxylic acid, (b) alcohol and (c) the compound 'X'.

An acid 'X' and an alcohol 'Y' react with each other in the presence of an acid catalyst to form a sweet smelling substance 'Z'. Identify 'X', 'Y' and 'Z'. Write the chemical equation for the reaction involved and name it. The substance 'Z' on treatment with sodium hydroxide produces back the alcohol 'Y' and sodium ethanoate. Write the chemical equation for the reaction involved and name it, giving justification for the name.

(i) A compound 'A' with a molecular formula of C₂H₄O₂ reacts with a base to give salt and water. Identify 'A', state its nature and the name of the functional group it possesses. Write chemical equation for the reaction involved. (ii) When the above stated compound 'A' reacts with another compound 'B' having molecular formula C₂H₆O in the presence of an acid, a sweet smelling compound 'C' is formed. (1) Identify 'B' and 'C'. (2) State the role of acid in this reaction. (3) Write chemical equation for the reaction involved.

Ethanol, C₂H₅OH is heated with alkaline potassium permanganate to give a compound X.
