Unformatted text preview: Nomenclature How to Name Organic Compounds This guide has organized the naming of organic compounds in five parts. You should name molecules starting backwards from this list. For example, determine functional group first, then saturation, then the parent chain, then the substituents, and then the stereoisomer characteristics: Stereoisomer Characteristics Substituents Parent Chain Bond Types Functional Groups 1. Stereoisomer Characteristics a. Cis (Z) /Trans (E) i. Identifies configuration of double bond ii. For Cis/Trans, you need identical groups on either side of the double bond 1. Cis – identical groups on same side 2. Trans – identical groups on opposite sides iii. For (Z)/(E), you need priority numbers 1. (Z) – The higher priority groups are on the same side 2. (E) – The higher priority groups are on opposite sides iv. (3E) – Give number to indicate location of double bond. For this case, the double bond is between carbon #3 and #4 b. (R)/(S) i. identifies configuration of stereocenters...
