Amine compounds Primary amines

Primary amine-containing-NH2 bound to the hydrocarbon chains or rings. You can think of amines as derivatives of ammonia, NH3. In primary amines, one of the hydrogen is replaced by hydrocarbons.

Example 1: Write the structural formula of ethylamine.

In this case, an ethyl group attached to the-NH2.

This name (ethylamine) there is no problem as long as there is no unambiguous meaning of the location-NH2. But it is like you have a 3-carbon chain in this case-NH 2 can be at either end or the middle.

Example 2: Write the structural formula for 2-aminopropane.


Indicate the name of the three carbon chain attached to the amino carbon into two. Amino-NH2 show.

Ethylamine (example 1) can also be called aminoethane.




Secondary and Tertiary Amine

In two of the secondary amine hydrogen atoms in ammonia is replaced by hydrocarbons. and three hydrogen replaced by a tertiary amine.

Example 1: Write the structural formula for dimethylamine.

In this case the two hydrogen atoms replaced by methyl groups.



Example 2: Write the structural formula for trimethylamine.

Here are three hydrogens in ammonia are replaced by methyl groups.
