Question
A neutral organic compound is warmed with some ethanoic acid and a little of conc. H2SO4. Vapours having sweet smell (fruity smell) are evolved. What type of functional group is present in this organic compound?
Solution
The functional group present in this organic compound is the alcohol (hydroxyl) group (-OH). When a neutral organic compound of alcohol group such as ethanol (C2H5OH) is warmed with some ethanoic acid, in the presence of a small quantity of concentrated sulphuric acid, a sweet smelling ester is produced.

Two statements are given - one labelled Assertion (A) and the other labelled Reason (R).
Assertion (A): Esterification is a process in which a sweet-smelling substance is produced.
Reason (R): When esters react with sodium hydroxide an alcohol and sodium salt of carboxylic acid are obtained.
