The correct Answer is:
To solve the problem, we need to analyze the reaction between phenol (PhOH) and chloroform (CHCl₃) in the presence of sodium hydroxide (NaOH), followed by acidic hydrolysis of the product formed. ### Step-by-Step Solution: 1. **Identify the Reactants:** - The reactants are phenol (PhOH) and chloroform (CHCl₃) in the presence of sodium hydroxide (NaOH). 2. **Reaction Mechanism:** - Sodium hydroxide acts as a base and abstracts a proton (H⁺) from phenol, generating a phenoxide ion (PhO⁻). - The phenoxide ion is a good nucleophile and can attack the electrophilic carbon in chloroform, which has three chlorine atoms attached. 3. **Formation of the Intermediate:** - The attack of the phenoxide ion on chloroform leads to the formation of a carbene intermediate (CCl₂), which is a neutral species with a valence of 2. - This carbene can react further to form a product. 4. **Formation of Salicylate:** - The phenoxide ion attacks the carbene, resulting in the formation of a compound where the phenolic group is ortho to the carbene (CCl₂) group, leading to the formation of ortho-chlorophenol. 5. **Acidic Hydrolysis:** - The product formed (ortho-chlorophenol) undergoes acidic hydrolysis. In this step, the chlorine atom acts as a good leaving group. - The acidic conditions facilitate the removal of the chlorine atom, leading to the formation of salicylic acid (C₇H₆O₃). 6. **Final Product:** - The final product after acidic hydrolysis is salicylic acid (C₇H₆O₃). ### Final Answer: The product of the reaction of phenol with chloroform in the presence of sodium hydroxide, followed by acidic hydrolysis, is salicylic acid (C₇H₆O₃). ---
