TestHub · Accepted Answer

lone pair delocalized so less basic than aniline.

$- M$ effect of $- N O_{2}$ decrease the basicity so it is less basic than aniline.

$- C H_{3}$ group at ortho so ortho effect exert here hence basic character decrease as compare to aniline.

Lone pair of $- N$ involve in delocalization and ring become aromatic due to this so it is also less basic then aniline.

$N H_{3}$ is more basic then aniline because phenyl group exert $- I$ effect.

$(v)$ is derivative of guanidine so they are more basic than aniline.
