Naming organic compounds can be a bit daunting, as there are a lot of rules and the names just get longer as the molecules get more complex, even if it is something familiar to you. Do you recognise the following names?
Once you get the hang of it, naming organic compounds is really very easy, and I will demonstrate with the following molecule:
First thing to do is find the longest carbon chain.
Then identify what functional groups, (if any) are present:
Now we number the carbons on the chain, so that the largest number of substituents have the lowest number:
Now we put it all together remembering that we order the substituents alphabetically, a hyphen goes between a number and a letter, a comma goes between two numbers and there shouldn’t be any spaces, (except when the functional group requires it).
So… that gives us: 2-chloro-5-methylheptane!
Here are some links to some practice questions:
