Vedclass · Answer

(D) The conversion of phenol to salicylic acid can be achieved through several methods:$1$. Kolbe-Schmitt reaction: Phenol reacts with $CO_2$ under pressure in the presence of an alkali $(NaOH)$ to form sodium salicylate,which upon acidification yields salicylic acid.$2$. Reimer-Tiemann reaction with $CCl_4$: Phenol reacts with $CCl_4$ in the presence of an alkali $(NaOH)$ to form salicylic acid directly.$3$. Reimer-Tiemann reaction with $CHCl_3$: Phenol reacts with $CHCl_3$ and alkali to form salicylaldehyde,which can then be oxidized to salicylic acid.Since all these methods can lead to the formation of salicylic acid,the correct answer is $D$.
