Vedclass · Answer

(C) In an aqueous medium,the basicity of methyl-substituted amines is determined by a combination of inductive effect,solvation effect,and steric hindrance.For methyl-substituted amines,the order of basicity is $(CH_3)_2NH > CH_3NH_2 > (CH_3)_3N > NH_3$.$1$. $(CH_3)_2NH$ (dimethylamine) is the most basic due to the combined effect of the $+I$ effect of two methyl groups and sufficient solvation.$2$. $CH_3NH_2$ (methylamine) is next.$3$. $(CH_3)_3N$ (trimethylamine) is less basic than expected due to steric hindrance which prevents effective solvation of the protonated cation.$4$. $NH_3$ (ammonia) is the least basic among these.

Which of the following represents the correct order of basicity in an aqueous medium?
