Vedclass · Answer

(C) The $pK_b$ value is inversely proportional to the basic strength of the amine. $A$ lower $pK_b$ value indicates a stronger base.In the aqueous phase,the basicity of ethyl-substituted amines follows the order: $(C_2H_5)_2NH > C_2H_5NH_2 > (C_2H_5)_3N > NH_3$.However,comparing the given options: $CH_3NH_2$ $(pK_b = 3.36)$,$CH_3CH_2NH_2$ $(pK_b = 3.29)$,$(CH_3CH_2)_3N$ $(pK_b = 3.25)$,and $(CH_3CH_2)_2NH$ $(pK_b = 3.00)$.Thus,diethylamine $(CH_3CH_2)_2NH$ has the lowest $pK_b$ value,making it the strongest base among the choices.
