Vedclass · Answer

(A) The given reaction is the Reimer-Tiemann reaction,where phenol reacts with chloroform $(CHCl_3)$ in the presence of an aqueous base $(NaOH)$ to form salicylaldehyde.In the first step of this reaction,chloroform reacts with the hydroxide ion to form the trichloromethyl anion,which then loses a chloride ion to generate dichlorocarbene $(:CCl_2)$.Dichlorocarbene is an electron-deficient species with a sextet of electrons,making it a strong electrophile that attacks the phenoxide ion.

Which of the following is the electrophile involved in the given reaction?
