ethyl amine
ethanol
acetamide
Which will not go for diazotisation?
C6H5NH2
C6H5CH2NH2
B.
C6H5CH2NH2
Only 1° aromatic amine (primary aromatic amine) form diazonium salts at low temperature (0°- 5C). A reaction in which -NH2 group is converted into diazo group () is called diazotisation. Diazotised salts are stable in cold aqueous solution.
aromatic primary amines, so undergo diazotisation but C6H5CH2NH2 (aliphatic amine) will not undergo diazotisation.
