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

  • CH3NH> (CH3)2NH >(CH3)3

  • (CH3)2NH> CH3NH> (CH3)3N


D.

(CH3)2NH> CH3NH> (CH3)3N

In aqueous solution, electron donating inductive effect, solvation effect (H-bonding) and steric hindrance all together affect basic strength of substituted amines.
