प्रश्न
Arrange the following in the increasing order of their pKb values:
C6H5NH2, C2H5NH2, C6H5NHCH3
उत्तर
Order of pKb values-
C2H5NH2 < C6H5NHCH3 < C6H5NH2
This is simply because +I effect of C2H5 group increases the basicity of amine while -I effect of C6H5 group decreases the basicity of Amine.
