Rank the amines from most basic to least basic.

Question

Quizplus · Accepted Answer

In order to rank amines by basicity, we need to consider the ability of the nitrogen to donate a lone pair of electrons to a proton. This ability is influenced by the electron-donating or electron-withdrawing groups attached to the nitrogen. Amine C has two electron-withdrawing chlorine atoms attached to the nitrogen, which decreases its ability to donate electrons and makes it the least basic. Amine A has two electron-donating methyl groups attached to the nitrogen, which increases its ability to donate electrons and makes it the most basic. Amine B has only one methyl group, so it is less basic than Amine A but more basic than Amine C. Therefore, the correct ranking is C > A > B.
