Electrophile is a molecule that forms a bond to its reaction partner which is the nucleophile by accepting both the bonding electrons from that reaction partner. Electrophilic reagents are said to be Lewis acids. Carbon dioxide is said to be an example of an electrophile.Complete answer:In this reaction, phenol reacts with chloroform and sodium hydroxide to give benzoic acid.${C_6}{H_5}OH + CHC{l_3} + NaOH \to {C_6}{H_4}(CHO)OH$The reaction for the electrophile can be given by.$NaOH + CC{l_3}^ - \to :CC{l_2} + NaC{l^ - } + {H_2}O$Additional information:The mechanism of the Reimer – Tiemann reaction is as follows. Chloroform which is on the reaction side is deprotonated by a strong base which can be sodium hydroxide or potassium hydroxide to form the chloroform carbanion which will quickly alpha-eliminate to give dichlorocarbene. The hydroxide can also deprotonate the phenol to give a negatively charged phenoxide. The negative charge is delocalized into the aromatic ring, making it more nucleophilic. Nucleophilic attack on the dichlorocarbene gives an intermediate dichloromethyl substituted phenol. After hydrolysis, the desired product is formed. Hence the correct option is B which is dichlorocarbene.Note: Dichlorocarbene is the reactive intermediate with the chemical formula $CC{l_2}$ . It is a common intermediate which is being produced from chloroform. Salicylaldehyde can be prepared from phenol and chloroform by heating with either potassium hydroxide or sodium hydroxide this reaction is called the Reimer - Tiemann reaction. Reimer–Tiemann reaction is a chemical reaction which is used for the formation of phenols at the ortho position.Recently Updated PagesComplete reduction of benzene diazonium chloride with class 12 chemistry CBSEHow can you identify optical isomers class 12 chemistry CBSEThe coating formed on the metals such as iron silver class 12 chemistry CBSEMetals are refined by using different methods Which class 12 chemistry CBSEWhat do you understand by denaturation of proteins class 12 chemistry CBSEAssertion Nitrobenzene is used as a solvent in FriedelCrafts class 12 chemistry CBSEComplete reduction of benzene diazonium chloride with class 12 chemistry CBSEHow can you identify optical isomers class 12 chemistry CBSEThe coating formed on the metals such as iron silver class 12 chemistry CBSEMetals are refined by using different methods Which class 12 chemistry CBSEWhat do you understand by denaturation of proteins class 12 chemistry CBSEAssertion Nitrobenzene is used as a solvent in FriedelCrafts class 12 chemistry CBSE
