e.g.,

cis-2,6-dimethylcyclohexanone

• highest priority functional group determines the suffix
• click for functional group priorities
• if no functional groups are present, procede to the next step

e.g.,

4,5-dimethyl-2-hexanone

• the longest chain (attached to group) determines the parent name
• parent name is modified by unsaturation (-ane to -ene or -yne)
• click for parent names

e.g.,

cis-2,6-dimethylcyclohexanone

• for monocyclic systems the size of the ring determines the parent name
• parent name is modified by unsaturation (-ane to -ene or -yne)
• click for naming more complex ring systems

e.g.,

cis-2,6-dimethylcyclohexanone

• start the numbering closest to the principal group
• use locants to specify location wherever necessary
• alphabetize substituents (without multiplicity prefixes; dimethyl = m)
• click for more rules

e.g.,

cis-2,6-dimethylcyclohexanone

• look for
  • multiple substituents on rings
  • multiple substituents on double bonds
  • stereocenters
• use locants to specify location wherever necessary
