Nomenclature, or the naming of organic compounds, is a key requirement in any organic chemistry course. You will start out with the basics, being tested on naming molecules and drawing molecules from a given name.
But it doesn’t stop there. As you proceed with your organic chemistry course you will be tested on reactions and mechanisms, but may find yourself faced with the name of a molecule instead of its drawing. No matter how many times you practiced a mechanism, if you don’t know your starting molecule, you won’t be able to answer related questions.
Despite the importance of nomenclature, this topic is often rushed in the orgo curriculum and textbook. That’s why I created this 21-video series to take you through naming step by step using my Puzzle Piece Approach. This will help you find patterns and see the logic with every additional concept and rule.

You must first recognize functional groups in order to name molecules. These groups influence reactivity as you progress in the course. This video will take you through all the common groups with tips & mnemonics to help you recognize and differentiate between the tricky ones. Try my Functional Groups Practice Quiz!
The rules for naming organic compounds are tedious and can become overwhelming fast. The first video shows you how to break down the name of an organic molecule using my ‘puzzle piece approach’. This video is a MUST for breaking down nomenclature in a simple and fun-to-solve manner.
This video teaches you how to name/recognize a simple or straight-chain alkane. Including examples of straight chain alkanes presented in condensed molecular formula, structural formula, and line or skeletal structure.
The complexity starts when we add a ‘branch’ or carbon substituent. This videos teaches you how to tackle molecules with one or more alkyl substituents/branches. Examples include single substituent to multiple same and varied branches
You may find a molecule containing a branched branch, or a substituent containing its own substituents. These can get tricky to name, but there are accepted ‘shortcuts,’ explained in this video! Examples include ispropyl, isobutyl, secbutyl, and tert butyl substituents.
Cycloalkanes have the first and last carbon of the chain fused. One cycloalkane follows the same naming pattern with a few differences. However, more than one fused ring has a drastically different naming pattern. Examples include single, fused, & substituted cyclic compounds.
A single pi bond introduced into the organic compound calls for a slight change in the naming pattern. This video shows you how to name with one or more double bonds while still following my ‘puzzle piece’ approach.

If a molecule contains alkenes or alkynes, you know what to do from Videos 6 & 7. But what do you do when the molecule contains BOTH! This is explained with a few examples in the ene + yne = enyne video.
*Organic Chemistry Functional Groups*
Videos 1-8 focus on the naming basics, videos 9-21 focus on naming functional groups that show up within organic compounds. If you’re not fully confident with the name or structure of the different functional groups – grab my FREE Organic Chemistry Functional Groups Cheat Sheet
