The correct order of basic strength among p-nitroaniline (I), p-bromoaniline (II), p-toluidine (III) is

View answer and explanation

Correct option: A

<

<

III

Electron-withdrawing groups decrease basicity, while electron-donating groups increase basicity. NO2 is strongly electron-withdrawing, Br is electron-withdrawing, and CH3 is electron-donating. Therefore, the correct order is I < II < III, making option A the correct answer.
