Esters are sweet smelling compounds.                                         

They are formed by the reaction of a carboxylic acid with an alcohol in the presence of conc. sulphuric acid.    

For example, ethyl ethanoate is prepared by reacting ethanoic acid and ethanol in the presence of conc.sulphuric acid.
