When ethanol reacts with ethanoic acid in the presence of cone. H2SO4, a substance with fruity smell is produced. Answer the following:

(i) State the class of compounds to which the fruity- smelling compounds belong.


Write the chemical equation for the reaction and write the chemical name of the product formed.


(ii) State the role of cone. H2SO4 in this reaction.

(i) The fruity smelling compounds belong to the class of esters (Ethyl acetate).


The reaction of an alcohol with an acid to from ester and water is called as esterification.


CH3COOH (Ethanoic acid) + C2H5OH( Ethanoic acid) → CH3COOC2H5 (Ethyl Acetate)+ H2O


Here, the ester formed is Ethyl Acetate. It is a sweet smelling ester.


(ii) The concentrated H2SO4 acts as a catalyst and a dehydrating agent and helps in the removal of water formed in the reaction between alcohol and carboxylic acid.
