Question

How will you convert Aniline to Flourobenzene?

Answer 1

ANSWER:

Aniline can be converted to flurobenzene by first converting it to diaazonium salt and then carrying out yhe Balz -Schiemann reaction.

STEP-1:  Reaction of aniline with     NaNO₂ + HCl

          at 0-5°C temperature forms benzene diazonium chloride(Diazotisation

          reaction)

STEP-2:  Reaction of BDC with HBF₄ gives an intermediate product which on        

               heating gives flurobenzene .
