C2H5OCH3
(CH3)2CHOC2H5
C6H5NH2
C6H5NO2
Nitrobenzene on reduction with zinc and NH4Cl gives
azobenzene
aniline
hydrazobenzene
N-phenyl hydroxylamine
In Gattermann reaction, a diazonium group is replaced by using . and are-
- ; - Cu/ HCl
- ; - CuCl2/ HCl
- ; - CuCl2/ HCl
- Cl2 ; - Cu2O/ HCl
Yellow dye can be prepared by a coupling reaction of benzene diazonium chloride in acidic medium with X. Identify X from the following.
Aniline
Phenol
Cumene
Benzene
A.
Aniline
Aniline and other arylamines are usually colourless, but get coloured on storage due to atmospheric oxidation. Yellow dye can be prepared by coupling reaction of benzene diazornum chloride in acidic medium with aniline.
Acid hydrolysis of methyl isocyanide gives
CH3NH2 + HCOOH
CH3NH2 + CH3COOH
CH3NH2 + CH3CH2COOH
CH3NH2 + (CH3)2CHCOOH
