Among the following sets of reactions, which one produces anisole?

1. $\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{H}\mathrm{O};\mathrm{R}\mathrm{M}\mathrm{g}\mathrm{X}$
2. ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{O}\mathrm{H};\mathrm{N}\mathrm{a}\mathrm{O}\mathrm{H};\mathrm{C}{\mathrm{H}}_3\mathrm{I}$
3. ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{O}\mathrm{H};$ neutral $\mathrm{F}\mathrm{e}\mathrm{C}{\mathrm{l}}_3$
4. ${\mathrm{C}}_6{\mathrm{H}}_5-\mathrm{C}{\mathrm{H}}_3;\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{C}\mathrm{l};\mathrm{A}\mathrm{l}\mathrm{C}{\mathrm{l}}_3$

Solution

$\left(1\right)$

$\left(2\right)$

(Williamson's synthesis)
$\left(3\right)$ ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{O}\mathrm{H}+$ neutral $\mathrm{F}\mathrm{e}\mathrm{C}{\mathrm{l}}_3\to$ Violet colour complex
$\left(4\right)$ ${\mathrm{C}}_6{\mathrm{H}}_5-\mathrm{C}{\mathrm{H}}_3+\mathrm{C}{\mathrm{H}}_3\mathrm{C}\mathrm{O}\mathrm{C}\mathrm{l}+\mathrm{A}\mathrm{l}\mathrm{C}{\mathrm{l}}_3\to$ Para-methyl acetophenone.
