Cycloalkanes with one ring and two or more substituents:
1. Numbering the carbons in the ring, starting at the carbon with the substituent
that is first in the alphabet and number in the direction that gives the next
substituent the lower number possible.
2. When there are three or more substituents, begin at the substituent that leads to
the lowest set of numbers (locants).
*The substituents are listed in alphabetical order, not according to the number of
their carbon atom.
