Arrange the amines in order of increasing basicity (weakest first).

Question

Quizplus · Accepted Answer

Basicity is directly proportional to the electron donating capacity of the substituent groups attached to the nitrogen atom. In this case, amine I has the highest basicity as it has three methyl groups that donate electrons to the nitrogen atom, making it more basic. Amine II has only two methyl groups, making it less basic than I. Amine III has only one methyl group, making it even less basic than II. Finally, amine IV has no methyl groups, making it the weakest base among the given options. Therefore, the correct order of increasing basicity is I > II > III > IV. Choice C lists the amines in the correct order.
