Amines Report Error

Solution:

Five compounds $(2,3,5,6$, and 7) are more basic than aniline.
(2) $\Rightarrow$ No delocalisation of lone pair of electrons on $N$ atom
(3) $\Rightarrow\left(- OCH _{3}\right)$ is EDG $(+ R >- I )$.
(5) $\Rightarrow$ Two $N$-atom with lone pairs
(6) $\Rightarrow$ Three $N$-atoms with lone pairs
(7) $\Rightarrow$ No delocalisation of lone pair of electrons on $N$-atom.
Moreover $1^{\circ}$ aliphatic amines are more basic than aniline
