Answer:
(i)
?is
electron-withdrawing group, decreases electron-density at N in ? hence
(A) less basic than aniline. ? is
electron-donating group increases electron density at N in ?hence (C)
more basic than aniline.
(ii)
As alkyl/aryl
part (hydrophobic part) increases solubility decreases. Solubility of 2° amine
is less than that of 1 ° amine.
