Vedclass · Answer

(B) The Reimer-Tiemann reaction involves the reaction of phenol with chloroform $(CHCl_3)$ in the presence of an aqueous base ($NaOH$ or $KOH$).In the first step,the base abstracts a proton from chloroform to form a trichloromethyl carbanion $(:CCl_3^-)$,which subsequently loses a chloride ion to generate dichlorocarbene $(:CCl_2)$ as an electrophilic intermediate.This dichlorocarbene then attacks the phenoxide ion to form the product.Therefore,the correct answer is $(B)$.
