Question

p methylaniline is more basic than p nitroaniline

Answer 1

due to the present of electron withdrawing group on nitroaniline which increases the tendency to produce hydrogen ions, but the latter has an electron donating group I.e methyl group. hence it is more basic than nitroaniline.

Answer 2

Hey dear,

● Explanation -
- Let's consider aniline as reference in this question.
- When electron donating group like methyl(-CH3) is at para position, electron density increases and thus basic character increases.
- When electron withdrawing group like nitro(-NO2) is at para position, electron density decreases and thus basic character decreases.
- Therefore, p-methylaniline is more basic than p-nitroaniline.
