Quizplus · Accepted Answer

Propanoic acid is the correct IUPAC name for the carboxylic acid containing three carbon atoms. The prefix "pro" denotes three carbon atoms, and the suffix "-anoic acid" indicates a carboxylic acid functional group. Choice A is incorrect because "1-" is unnecessary in the name since there is only one possible position for the carboxylic acid group on a three-carbon chain. Choice C is incorrect because "propionic" is not a valid IUPAC prefix. Choice D is incorrect because it does not specify the correct numbering for the three carbon atoms in the chain.
