HELLO AYUSH,
first i will give you the reaction and then i will explain you the reaction
C6H5NH2 + CHCl3 + 3KOH --------------> C6H5NC + 3KCl + 3H2O
BY adding the chloroform to the aniline in presence of alkaline potassium hydroxide ,then it will form phenylisocyanide with potassium chloride and water later these two are removed by simple distillation.
i will explain you the mechanism
------- this is the characteristic reaction of primary amines.Primary amines on reacting with chloroform and potassium hydroxide form the isocyanide compounds of foul smell gas which is often used to primary amine group in an organic compound.
secondary and tertiary amines will not give this test,
THANK YOU
