Why are 1°,2°,and 3° alkylamines more basic than ammonia (NH₃)? A)Because of the electron-withdrawing inductive effect of the alkyl groups B)Because of the steric hindrance of the alkyl groups C)Because of the resonance delocalization of the alkyl groups D)Because of electron-donating inductive effect of the alkyl groups

Question

Quizplus · Accepted Answer

The alkyl groups in 1°, 2°, and 3° alkylamines have an electron-donating inductive effect, which increases the electron density around the nitrogen atom. This results in greater basicity compared to ammonia. Additionally, steric hindrance (Choice B) can actually decrease basicity, while resonance delocalization of alkyl groups (Choice C) is not a relevant factor in this case.
