Organic Chemistry Functional Groups

This slide show will cycle on its own through all of the ochemlab functional groups and the ochem substituents. It will show a structural diagram and give you 4 seconds to think of the name. Then, it will show you the name for 4 seconds. Hopefully, it will help with

memorization. It will continually repeat until you press escape.

other by a methyl group?

A homologous series!

Rules of IUPAC

• ID longest chain of C atoms

• # based on end which has closer substituent; rule of first point of difference

• Name the substituents!
