Which of the following is the strongest base?
A) ammonia
B) dimethylamine
C) aniline
D) 4-nitroaniline

Question

Quizplus · Accepted Answer

Dimethylamine is the strongest base among the options given. This is because alkyl groups, like the methyl groups in dimethylamine, are electron-donating, which increases the electron density on the nitrogen atom, making it more likely to donate a pair of electrons and act as a base. Ammonia is less basic because it lacks these electron-donating groups. Aniline and 4-nitroaniline are even less basic due to the electron-withdrawing effect of the benzene ring and the nitro group, respectively, which decreases the electron density on the nitrogen, making it less likely to donate electrons.
