Name the following aldehyde.

Question

Quizplus · Accepted Answer

The name of the compound is derived from the parent chain, which is a five-membered ring with a methyl group attached at the 2 position. The suffix "-al" indicates that it is an aldehyde. Therefore, the correct name is 2-methylcyclopentanecarbaldehyde. Option A is incorrect because it does not specify that it is an aldehyde. Option B is incorrect because it suggests that the methyl group is attached to the cyclopentane ring at the 2 position, which is not the case. Option D is incorrect because it uses a non-standard naming convention (using "cyclopentanyl" instead of "cyclopentanecarbaldehye").
