Question

Quizplus · Accepted Answer

The common name for the compound is β-chlorobutyric acid. This is because the compound has a carboxylic acid functional group (-COOH) attached to a four-carbon chain with a chlorine atom (Cl) attached to the second carbon, which is the beta carbon. None of the other choices correctly identify the location of the chlorine atom on the chain. Choice A and D use lambda (λ) notation, which is not commonly used in naming organic compounds. Choice B uses beta (β) notation but incorrectly places the chlorine atom on the third carbon rather than the second. Choice E uses numerical notation, which is less preferred than using Greek letters.
