Some reactions of amines are given. Which one is not
correct ? [NEET Kar. 2013]
(a) (CH₃)₂NH + NaNO₂ + HCl → (CH₃)₂ N – N = O
(b) (CH₃)₂N – + NaNO₂ + HCl →
(CH₃)₂N⁻ – N = NCl
(c) CH₃CH₂NH₂ + HNO₂ → CH₃CH₂OH + N₂
(d) CH₃NH₂ + C₆H₅SO₂Cl → CH₃NHSO₂C₆H₅
Answers
Option (b) (CH₃)₂N – + NaNO₂ + HCl → (CH₃)₂N⁻ – N = NCl
is not correct reaction because the product formed in this reaction is P - nitroso aromatic compounds.
so, Option is our answer.

Classification of Amines
On the basis of the presence of replaceable hydrogen atoms, amines are of three types:
Primary Amines: when an alkyl or Aryl group replaces one of three hydrogen atoms.
Secondary Amines: when the alkyl or aryl group replaces two hydrogen atoms.
Tertiary Amines: when total three hydrogen atoms are replaced by alkyl or aryl group.
