Question
The correct increasing order of basic strength of the given molecules is: (I) (II) (III)
III < I < II
III < II < I
II < I < III
II < III < I
The basic strength of amines depends on the availability of the lone pair of electrons on the nitrogen atom for donation. Electron-donating groups (EDG) increase the electron density on nitrogen, making the amine more basic. Conversely, electron-withdrawing groups (EWG) decrease the electron density, making the amine less basic. In the standard NEET 2017 question this refers to, the structures are typically (I) Aniline, (II) p-Nitroaniline (which has a strongly electron-withdrawing group), and (III) p-Toluidine (which has an electron-donating group). Therefore, the p-nitroaniline is the least basic, and p-toluidine is the most basic. The correct increasing order is II < I < III.
This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from Amines. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
