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.

Naming organic compounds first requires a thorough understanding of organic chemistry functional groups.
This video will take you through all the common groups along with tips and mnemonics to help you recognize and differentiate between the tricky ones.

The rules for naming organic compounds are tedious and can become overwhelming fast. The first video in my naming series 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.
The simplest organic molecule consists of a carbon chain with single bound hydrogen atoms. This video shows you how to tackle the first part of the naming puzzle by teaching you how to name and recognize a simple or straight-chain alkane.
Practice examples include straight chain alkanes presented in condensed molecular formula, structural formula, and line or skeletal structure.
The first level of complexity for naming organic compounds comes from the addition of a ‘branch’ or carbon substituent. This videos teaches you how to tackle molecules with one or more alkyl substituents/branches.
Examples vary from single substituent to multiple of the same and varied branches.
In addition to naming branched alkanes, you may find yourself faced with a molecule containing a branched branch, or simply a substituent containing its own substituents.
While these branched branches are tricky to name, there are accepted ‘shortcuts’ explained in this video including examples containing ispropyl, isobutyl, secbutyl and tert butyl substituents.
Cycloalkanes are simply organic molecules in which the first and last carbon of the chain are fused. These molecules follow the same naming pattern with a few differences.
However, when faced with more than one fused ring, the naming pattern changes drastically.
This video takes you through the examples with step-by-step explanations for naming single and fused, and substituted cyclic organic 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 organic compounds containing one or more double bonds while still following my ‘puzzle piece’ approach.
When your organic compound contains two pi bonds between the same set of carbon atoms you have an alkyne. Naming an alkyne is no different compared to naming alkenes, with a slight change in the ‘last name’ of the molecule.
This video shows you how to tackle triple-bond bond naming with a few step by step examples.
If a molecule contains just alkenes or just alkynes, the naming follows the rules discussed in the above two videos.
But what do you do when the molecule in question contains both an alkene and an alkyne on the same compound?
This is explained with a few examples in the ene + yne = enyne video.
