The major product formed in the reaction given below will be:
Fate of aliphatic diazonium ion -
The diazonium ions of aliphatic amines are very unstable and produces carbocation immediately, which can produce different products.
Fate of aromatic diazonium ion -
Diazonium salts of aromatic amines are comparatively more stable and evolve nitrogen only on heating.These diazonium salts can be isolated at low temperatures.
As we know when Aq HCl in the presence of NaNO2 happens we get
