Q. The correct order of the basic strength of methyl substituted amines in aqueous solution is :
A) $(CH_3)_2NH > CH_3NH_2 > (CH_3)_3N$
B) $(CH_3)_3N > CH_3NH_2 > (CH_3)_2NH$
C) $(CH_3)_3N > (CH_3)_2NH > CH_3NH_2$
D) $CH_3NH_2 > (CH_3)_2NH > (CH_3)_3N$
Explanation
[Solution] In water, inductive, solvation and steric effects combine to give $2^\circ > 1^\circ > 3^\circ$ for methylamines. Answer (1).
