An aromatic organic compound [A] on heating with NH3 and Cu2O at high pressure gives [B]. The compound [B] on treatment with the ice-cold solution of NaNO2 and HCI gives [C], which on heating with Cu/HCl gives compound [A] again. Identify the compounds [A], [B] and [C]. Write the name of the reaction for the conversion of [B] to [C].
This process is called diazotization.
A – Chlorobenzene
B – Benzenamine or Aniline
C – Benzene diazonium chloride
Conversion of B to C is called Sand-Meyer reaction
