If x and y are the pKb values of p-methylaniline and N,N-dimethylanili

1.	If x and y are the pKb values of p-methylaniline and N,N-dimethylaniline, what is the relation between x and y?(a) x > y(b) x < y(c) x = y(d) x >> yThe question was asked in examination.The origin of the question is Amines Chemical Reactions topic in chapter Amines of Chemistry – Class 12
Answer» The correct answer is (a) x > y To EXPLAIN: The basicity of N-methyl anilines is very slightly higher than that of ring SUBSTITUTED methyl anilines. This is because the methyl GROUP is directly attached to the N atom in N,N-dimethylaniline and the electron effect is more PRONOUNCED. But this is only a minute effect.
