Question

$C_6{H}_5{N}_{2}Cl\underset{HCl}{\overset{CuCl}{\to }}{C}_6{H}_{5}Cl$

Above reaction is :

• A. Gattermann's reaction
• B. Sandmeyer's reaction
• C. Wurtz's reaction
• D. Frankland's reaction

Answer 1

The correct option is B Sandmeyer's reaction

The Sandmeyer reaction is used to prepare aryl halides from aryl diazonium salts. It is named after the Swiss chemist Traugott Sandmeyer. The reaction is a method for substitution of an aromatic amino group via preparation of its diazonium salt followed by its displacement with a nucleophile, catalyzed by copper(I) salts.
