उत्तर
1 mL of ethanol and 1 mL of glacial acetic acid are taken in a test tube. 3-4 drops of concentrated sulphuric acid are then added to a test tube. The resulting mixture in a water bath is then heated (as shown in the figure) for 5 minutes. After this, the contents are poured in a beaker containing 20 mL water. A sweet-smelling compound (ethyl ethanoalte) will be obtained as the product.
