Above reaction is known as
Options
- AFittig reaction.
- BSandmeyer reaction.
- CKolbe reaction.
- DReimer-Tiemann reaction
Correct answer
B. Sandmeyer reaction.
Step-by-step solution
The given reaction shows the conversion of benzenediazonium chloride ( C₆H₅N₂^+Cl^- ) to chlorobenzene ( C₆H₅Cl ) using copper(I) chloride ( Cu₂Cl₂ ) as a reagent. This is a classic example of the Sandmeyer reaction, where an aryl diazonium group is replaced by a halide or pseudohalide (like Cl^- , Br^- , or CN^- ) in the presence of the corresponding copper(I) salt. Other reactions mentioned: Fittig reaction involves the coupling of two aryl halides using sodium metal. Kolbe reaction is the carboxylation of sodium
