Quizplus · Accepted Answer

The longest carbon chain in the compound is four, which makes it a butanoic acid. The chlorine atom is located in the third carbon from the carboxyl group, so the correct numbering gives us a 3-chlorobutanoic acid. Therefore, the correct IUPAC name is 3-chlorobutanoic acid. The options A, B, C, and D are incorrect because they do not consider the carboxyl group and/or the correct position of the chlorine atom.
