If hydroxyl function of carboxylic acids is replaced by other functional group, they are named as derivatives of carboxylic acids. <> Since this sodium salt of propanoic acid - so start from propanoic acid is a three carbon acid with no carbon-carbon double bonds and this negative ion without the H+ atom is called propanoate. •A carboxylic acid contains the –COOH and in amide the –OH part of the carboxylic acid is replaced by the –NH 2 (amino) group so amide contain the -CONH 2 group. These are generally represented as, where Z is halogen (usually Cl), OCOR’, OR’ or NH 2 (or NHR’ or NR 2 ‘). Carboxylic Acid Nomenclature Acids are named by replacing the "e" with "oic" and then adding the word "acid". Ethanoic acid will react with ethanol in the presence of concentrated sulfuric acid (catalyst) to form ethyl ethanoate: CH 3 COOH + C 2 H 5 OH → CH 3 COOC 2 H 5 + H 2 O . There are many common names for carboxylic acids that are in use. 4 0 obj (b) When Z is -OR’, the derivatives are called as esters. 1 0 obj possess two carboxylic acid groups and are named as dioic acids whereas, if the two carboxylic acid groups are in the benzene ring it is named as dicarboxylic acid as shown for compound 13. Naming carboxylic acid follows certain pattern for example the structural formula for the compound. Chapter 18 covered in the semester on carboxylic acid derivatives.
