Question

Question: Classify each amine in the following compounds as ${\mathbf{1}}^{\mathbf{0}}$, ${\mathbf{2}}^{\mathbf{0}}$or ${\mathbf{3}}^{\mathbf{0}}$.

a.

b.

Short answer

Answer

a.

b.

Step-by-step solution

Amine

Amines are nitrogen containing compounds.The functional group in amine is$\mathit{N}{\mathit{H}}_{\mathbf{2}}$ . The hydrogen atoms are replaceable with the same number of alkyl groups.

Step 2:Classification of amines in a compound

The classification of amines are as follows:

• If the nitrogen in$N{H}_2$group is attached withone carbon, then the compound is known as$1^0$ amine.
• If the nitrogen in $N{H}_2$group is attached with two carbon atoms by replacing one hydrogen, then the compound is known as $2^0$ amine.
• If the nitrogen in $N{H}_2$group is attached with three carbon atoms by replacing two hydrogens, then the compound is known as $3^0$ amine.

Explanation

a. The $1^0$, $2^0$and $3^0$classification of amines are represented as:

Classification of$1^0$and $2^0$amines

b. The $1^0$, $2^0$and $3^0$classification of amines are represented as:

Classification of $3^0$amine
