The names of organic molecules are derived from the simplest of organic families: the alkanes.
You will need to learn how to name molecules up to five carbons long. There is no easy way to do this - you have got to learn them.
|Code||Number of carbons|
Whilst it is relatively easy to name linear molecules, what happens if there are branches in the chain? What happens if the OH group is attached to the second carbon in the chain?
The following rules enable us to identify any organic compound with a unique name:
Full name: 2-methylbut-1-ene
Any repeat groups within the molecule need the prefix di-(two), tri-(three) or tetra-(four), eg CH3C(CH3)2CH3 – dimethylpropane.
