Ans: (C)
Because of the electron-releasing nature of the alkyl group, it (R) pushes electrons towards nitrogen, making the unshared electron pair more available for sharing with the acid's proton. Furthermore, the +I effect of the alkyl group stabilizes the substituted ammonium ion formed from the amine by dispersing the positive charge.
As a result, alkylamines are more powerful bases than ammonia.
As a result, the basic nature of aliphatic amines should increase as the number of alkyl groups increases.
