प्रश्न
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?
उत्तर
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.
