Question

Explain the classification of amine compounds.

✓

Answer

→Amine compounds are classified as primary (1⁰) secondary (2⁰) and tertiary (3⁰) depending upon the number of hydrogen atoms replaced by alkyl or aryl groups in ammonia molecule.
→If one hydrogen atom of ammonia is replaced by R or Ar, we get RNH₂ or ArNH2 a primary amine (10)
→If two hydrogen atoms of ammonia or one hydrogen atom of R - NH2 are replaced by another alkyl/aryl (R') group we get secondary amine $\left(2^0\right) R - NH - R ^{\prime}$
→The second alkyl/aryl group may be same or different
→Replacement of another hydrogen atom by alkyl/aryl group leads to the formation of tertiary amine $\left(3^0\right)$.

Primary $\left(1^{\circ}\right)$ secondary $\left(2^{\circ}\right)$ tertiary $\left(3^{\circ}\right)$
→Amines are said to be 'simple' when all the alkyl or aryl groups are the same, and 'mixed' when they are different.
