Question

Dhanya heated Ethanol with a compound A in the presence of a few drops of concentrated sulphuric acid and observed a sweet smelling compound B is formed. When B is treated with sodium hydroxide , it gives back Ethanol and compound C. Identify compounds A, B and C .Write the chemical reactions involved and name the reactions.

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'.

Define Esterification and Saponification . Give their reactions also.

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.
