IUPAC name for the given propanoic acid salt has to be chosen from the given options. Concept Introduction: Carboxylic acid salts when treated with a strong acid produces carboxylic acid as the product. Carboxylic acid salts contain two ions. They are a negative carboxylate ion and a positive ion. When naming the carboxylic acid salt, the positive ion is named first that is followed by the carboxylate name. The carboxylate is named from the parent carboxylic acid by replacing the suffix “-ic acid” with “-ate”.
