What is the IUPAC name of the compound below?

Question

Quizplus · Accepted Answer

The compound is a cyclohexanone with a pentyl group (5-carbon chain) attached at the 3-position and a chlorine atom attached at the 4-position. The name should start with "4-chloro-3-pentyl-" and end with the base name of the parent cyclohexanone structure, which is "cyclohexanone". Therefore, the correct name is "4-chloro-3-pentylcyclohexanone". Option A is incorrect because it incorrectly indicates 1 instead of 3 position for pentyl group, option C is incorrect because it mentions the positions of the substituents in incorrect order and option D is incorrect because it indicates "phenone" instead of "cyclohexanone".
