What happens when :
(a) Salicylic acid is treated with `(CH_(3)CO)_(2)O""//H^(+)`?
(b) Phenol is oxidised with `Na_(2)Cr_(2)O_(7)//H^(+)`?
(c) Anisole is treated with `CH_(3)Cl` / anhydrous `AlCl_(3)`?

Text Solution

Verified by Experts

(a) Salicylic acid is treated with acetic anhydride in the presence of `H^(+)` to give aspirin.

(b) Phenol is oxidised with `Na_(2)Cr_(2)O_(7)//H^(+)` to give benzoquinone.

(c) Anisole on treatment with `CH_(3)Cl` in the presence of anhydrous `AlCl_(3)` gives o-and p-methyl anisole.
