Question

Classify the given amines a primary, secondary or tertiary:

Answer 1

Amines are organic compounds derived from ammonia ($N{H}_3$). They are derived by replacing its one or more hydrogen atoms by alkyl or aryl groups.

Amines are classified into 3 categories

(1)primary amines

In primary amines, one hydrogen atom of $N{H}_3$ is replaced by an alkyl or aryl group.

(2) secondary amines

In secondary amines, two hydrogen atoms of $N{H}_3$ are replaced by alkyl or aryl groups.

(3) In tertiary amine, all the three hydrogen atoms of $N{H}_3$ are replaced by alkyl or aryl groups.

Classification of the given amines are:

(iii) $(C_2{H}_5{)}_{2}CH{NH}_2$ ------ Primary amine

(iv) $(C_2{H}_5{)}_{2}NH$ ------- Secondary amine
