  37. Naming cycloalkanes
    When a cycloalkane has 2 or more substituted groups, the ring is numbered to give the location of the substituted group the smallest #.
  38. Prefixes when cycloalkanes consist of 2 or more substituted groups.
    • -Di, tri, tetra are used along with
    • -Cis (same), and trans (opposite) are used.
    • (e.g. cis-1,3-dimethyclcyclohexane, trans-1,2-dimethylcyclohexane).
