Step-by-step solution
(A) When phenol is distilled with Zn - dust, it gives benzene. it is an example of reduction. Phenol loses one O atom. (B) When phenol is treated with CHCl 3 and NaOH followed by acidification, salicyaldehyde is formed. The reaction is known as Reimer Tiemann reaction. (C) Reaction of phenol with sodium hydroxide and carbon dioxide is Kolbe's Schmidt reaction that is a electrophilic substitution reaction resulting in the formation of salicylic acid as shown in the reaction.
