Basicity of AminesAmines
Compare the basic strength of Aniline, N-Methylaniline, and N,N-Dimethylaniline. Does adding methyl groups to the nitrogen increase or decrease basicity?
Expert Answer
Basicity Increases. Order: -Dimethylaniline > -Methylaniline > Aniline. Reason: The methyl groups are electron-releasing (+I effect). They increase the electron density on the Nitrogen atom, making the lone pair more available compared to unsubstituted Aniline.
