An azo compound is formed when benzene diazonium chloride reacts with:
2,4,6-Trimethylphenol
Phenol
Both (A) and (B)
Aniline
Both aniline and phenol react with benzene diazonium chloride to undergo coupling reaction to give azo compound.
When Aniline is treated with Nitrous acid, which is prepared
in situ
from Sodium Nitrite and mineral acid, the product formed is:
C6H5NH2+HCl+NaNO2→ _____________ + 2H2O
