IUPAC Rules For Naming Organic Compounds with Functional GroupsReference: 24.4(pg. 1026-8,1030-1) (Ignore “Carbohydrates”, “Ester groups in polymers” and “Esters in living systems”) Reference: 24.5(pg. 1032-5) (Main sections of “Amines” and “Amides” only) The naming of hydrocarbons follows a few basic rules. However, when organic molecules contain functional groups, the situation is more complex. Often, the rules for naming molecules with functional groups are cumbersome. For example, what about an alkene with an OH group attached to it? Where should the numbering of carbons start? Does the carbon attached to the alcohol get the lowest number, or is it the carbon involved in the double bond? There are IUPAC rules for naming complex molecules like this. However, our focus will be limited to naming simple molecules with only one functional group.
