Cycloalkane Nomenclature

Ringed structures are easy to name, you just need to use a new prefix (aka –cyclo)!

Hint: Benzene and a cyclohexane are NOT the same thing. Remember, benzene has double bonds in it!

Understanding Cycloalkanes

In general, we assign the root name to the portion of the alkane that has the greater number of carbons

Example: Determine the root carbon name for the following structure 

1m

Example: Determine the root carbon name for the following structure 

1m

Numbering Monocyclic Cycloalkanes

If you only have one substituent on your ring, the numerical location is unnecessary! 

Great job! Did you remember to include the location for the first example? Remember, that location is not optional!

Introduction to Bicyclics

Bicyclics are also forms of cycloalkanes, but since they are not monocycles, they have completely different rules for naming! (See next topic)
