(a) Sandmeyer reaction (b) Gattermann reaction
(c) Claisen reaction (d) Carbylamine reaction

Answer 1

The reaction Ar N₂Cl⁻ (→┴(Cu/HCl) ) ArCl + N₂ + CuCl is

named as Sandmeyer reaction

• The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts using copper salts as reagents or catalysts.

• It is an example of a radical-nucleophilic aromatic substitution

• The reaction was discovered in 1884 by Swiss chemist Traugott Sandmeyer, when he attempted to synthesize phenylacetylene from benzenediazonium chloride and cuprous acetylide.

•Instead, the main product he isolated was phenyl chloride.
