The correct order of the basic strength of methyl substituted amines in aqueous solution is :
(CH3)3N > CH3NH2 > (CH3)2NH
(CH3)3N > (CH3)2NH> CH3NH2
CH3NH2 > (CH3)2NH >(CH3)3N
(CH3)2NH> CH3NH2 > (CH3)3N
D.
(CH3)2NH> CH3NH2 > (CH3)3N
In aqueous solution, electron donating inductive effect, solvation effect (H-bonding) and steric hindrance all together affect basic strength of substituted amines.
Basic character :
(CH3)2NH> CH3NH2 > (CH3)3N
