What are the common names we need to know for the final?
I know we should know iso, neo and tert since we went over those in detail in class.
What about sec? What's difference between sec and neo... they both look like T-shapes to me.
Is there any other common names we should know?

sec means that the substituent branches at the first carbon (secondary). neo is more like a tert, referring to a substituent whose second-to-last carbon of the chain is trisubstituted (has 3 methyl groups attached to it), and is used for substituents with 5 carbons or higher.
