Question
Considering the basic strength of amines in aqueous solution, which one has the smallest pKb value?
Options
A.(CH3)2NH
B.CH3NH2
C.(CH3)3N
D.C6H5NH2
Solution
Among C6H5NH2, CH3NH2, (CH3)2NH,
(CH3)3N. C6H5NH2 is least basic due to resonance.
Out of (CH3)3N, CH3NH2, (CH3)2NH. (CH3)2NH is most basic due to +I effect and hydrogen bonding in H2O.
