Question

Quizplus · Accepted Answer

Piperidine is the most basic amine because it has a cyclic structure that allows for greater overlap of its lone pair of electrons with the adjacent carbons, thereby increasing its basicity. The other amines listed are not cyclic and do not have this advantage, with aniline being the least basic due to electron withdrawal by the benzene ring.
