Question

(C) In an aqueous solution, the basic strength of ethyl-substituted amines is determined by the interplay of three factors: the inductive effect ($+I$

Vedclass · Accepted Answer

$(C_2H_5)_2 NH > (C_2H_5)_3 N > C_2H_5NH_2 > NH_3$

Vedclass · Answer

(C) In an aqueous solution, the basic strength of ethyl-substituted amines is determined by the interplay of three factors: the inductive effect ($+I$ effect), the solvation effect (hydrogen bonding), and steric hindrance.For ethyl-substituted amines, the secondary amine $(2^\circ)$ is the most basic due to the optimal balance of these factors.The tertiary amine $(3^\circ)$ is less basic than the secondary amine due to steric hindrance, but more basic than the primary amine $(1^\circ)$.Thus, the correct order of basic strength is $(C_2H_5)_2 NH > (C_2H_5)_3 N > C_2H_5NH_2 > NH_3$.
