Amines 2

Now that you know the basics of numbering and naming, here is an example that LOOKS a little difficult.
When things are attached to the CARBON CHAIN, we use numbers.
But when things like Chlorine are attached to the Nitrogen in NH₂, we use the letter N to say the Chlorine is attached to the Nitrogen!

Notice that the Chlorine is attached to the Nitrogen and NOT to the carbons.
We don't use numbers for this chlorine
Instead we say that the chlorine is attached to an N.
Hence:
N-chloro.

Since the chain is 3 carbons long, and has an amine at the first carbon:
propan-1-amine

Hence the name is:
N-chloropropan-1-amine

Another example

So the name for this works as follows:

butan-2-amine
This is the 4 carbon chain

N,3-dichloro
There is a chlorine attached to N and at C-3

N-methyl
There is also a methyl attached at N

Hence the name is:
N,3-dichloro-N-methylbutan-2-amine
