JEE Main Chemistry question

Chemistry Amines JEE Main

Due to the (electron-donating inductive) effect of an alkyl group, the N-atom of an amine acquires a partial negative charge, and thus the lone pair is more easily donated. This explains

(A)Why aromatic amines are weaker bases than aliphatic amines
(B)Why aliphatic amines are stronger bases than ammoniaCorrect
(C)Why tertiary amines are always the strongest bases
(D)None of these

Answer: (B)

Solution

The effect of an alkyl group pushes electron density onto nitrogen, making its lone pair more available for donation (protonation)
