Amines contain nitrogen with replaceable hydrogen.The functional group in amine is $N{H}_2$. The alkyl groups replace the same number of hydrogen atoms in amine.

The functional group in alcohol is the hydroxyl (-OH) group.

The classification of amines is as follows:

• If the nitrogen is attached with one carbon is known as $1^0$ amine.
• If the nitrogen is attached to two carbon atoms is known as $2^0$ amine.
• If the nitrogen is attached with three carbon atoms, then the compound is known as $3^0$amine.

The classification of alcohol is as follows:

• The $1^0$alcohol is attached to $1^0$carbon.
• The $2^0$alcohol is attached to $2^0$carbon.
• The $3^0$alcohol is attached to $3^0$carbon.
