Naming hydrocarbons

When naming organic compounds:

• only the longest chain is included
• the parent chain must be in a straight line in the diagram
• the substituent groups are listed in numerical order
• the substituent groups are listed in alphabetical order

The general formulas for alkanes, alkenes and alkynes are:

• alkane: C_nH_2n+2

  alkene: C_nH_2n

  alkyne: C_nH_2n-2

• alkane: C_nH_2n

  alkene: C_nH_2n+2

  alkyne: C_nH_n+4

• alkane: C_nH_2n-2

  alkene: C_nH_2n

  alkyne: C_nH_2n+2

• alkane: C_nH_2n+2

  alkene: C_nH_2n

  alkyne: C_nH_n-4
