Quizplus · Accepted Answer

The substance has two cyclopentane rings attached to a central amine nitrogen. The prefix "N-" indicates that the substituent is attached to the nitrogen atom. The first cyclopentane ring is attached to the nitrogen atom and contains a methyl group, so it is named "N-methylcyclopentanyl". The second cyclopentane ring is also attached to the nitrogen atom and does not contain any substituents, so it is named "N-cyclopentanyl". The two cyclopentane rings are separated by the prefix "-N-". Finally, the parent chain containing the amine nitrogen and the attached rings is cyclohexane, so it is named "cyclohexanamine". Thus, the correct IUPAC name is N-cyclopentyl-N-methylcyclopentanamine.
