Carboxylic Acids

CARBOXYLIC ACIDS

Carboxylic acids start with finding the parent chain, replacing the -ane suffix and adding -anoic acid to the end of the chain. This will have a COOH group. In the case of having two COOH groups, the name will be -anedioic acid. For example, pentanedioic acid will be HOOCCH2CH2CH2COOH. The COOH will be at the end of the side chain. The carboxyl group will take precedence over double bonds, alkyl groups, and halogen substitutes. If the carboxyl group is attached to a ring, the suffix carboxylic acid is added to the molecule. If there is a double bond, the suffix will be enoic acid without numbering as the C1 will be the COOH molecule. Figure 26 shows what common carboxylic acids:
