A) The compound reacts with ethanol in presence of an acid to form a sweet smelling compound ’B'.
The compound is Ethanoic Acid (CH3COOH).
B) The chemical equation is
CH3COOH + C2H5OH = CH3COOC2H5 + H2O.
C) We can get back A from B by hydrolysis in the presence of an acid or base.
D) The process is called as Saponification.
The chemical equation as follows is
CH3COO2H5 + H20 ----- CH3COOH + C2H5OH.
E) In the process carbon dioxide gas is produced.
The compound is Ethanoic Acid (CH3COOH).
