Solution

Hi,

A neutral organic compound A is ethanol has molecular formula C₂H₆O on oxidation with potassium dichromate and sulphuric acid gives an acidic compound B which is ethanoic acid. The compound ethanol reacts with ethanoic acid in the presence of concentrated sulphuric acid to give a sweet smelling substance C which is ethyl ethanoate.

Reactions are given below :

CH₃CH₂0H + 2[0] ---------> CH₃COOH + H₂O

CH₃COOH + C₂H₅OH -----------------> CH₃COOC₂H5

A- Ethanol
B- Etanoic acid
C - ethyl ethanoate
