Which of the following reactions uses diazonium salt ?

Step-by-step solution

The Sandmeyer reaction involves the conversion of an aryl diazonium salt into an aryl halide using copper(I) salts, such as CuCl or CuBr . The Mendius reaction is the reduction of nitriles to primary amines using sodium and ethanol. The Hofmann rearrangement reaction involves the conversion of a primary amide to a primary amine with one fewer carbon atom using bromine and a strong base. The carbylamine reaction is a test for primary amines, where a primary amine reacts with chloroform and a base to form an isocyani
