- A$4 < 2 < 1 < 3$
- ✓$4 < 3 < 1 < 2$
- C$4 < 1 < 3 < 2$
- D$2 < 1 < 3 < 4$
✓
Answer
Correct option: B.
$4 < 3 < 1 < 2$
b
$(b)$ $\begin{matrix}
\,\,\,\,\,\,\,O \\
\,\,\,\,\,\,|| \\
(4)\,Ph-C-N{{H}_{2}} \\
\end{matrix}$ is weak base because of resonance.
$(b)$ $\begin{matrix}
\,\,\,\,\,\,\,O \\
\,\,\,\,\,\,|| \\
(4)\,Ph-C-N{{H}_{2}} \\
\end{matrix}$ is weak base because of resonance.
$(3)$ One to $-M$ of $NO_2$ and onho effect it is weak base.
$(2)$ Strong base lone pair is not involved in resonance.
