$(CH_{3})_{2}NH > CH_{3}NH_{2} > (CH_{3})_{3}N > NH_{3}$

Vedclass · Answer

(D) In the aqueous phase,the basic strength of amines is determined by a combination of three factors: inductive effect,solvation effect (solvation of the conjugate acid),and steric hindrance. For methyl-substituted amines,the order is $(CH_{3})_{2}NH > CH_{3}NH_{2} > (CH_{3})_{3}N > NH_{3}$. This is because the secondary amine $(CH_{3})_{2}NH$ has the optimal balance of inductive effect and solvation,while the tertiary amine $(CH_{3})_{3}N$ experiences significant steric hindrance,reducing its basicity compared to the secondary and primary amines.

In the aqueous phase,what is the correct order of basic strength for methyl-substituted amines?
