Question

What is the product of sandmeyer's reaction when primary amine is treated with cuprous bromide?​

Answer 1

Answer:

The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts using copper salts as reagents or catalysts. ... (Due to the low cost of copper salts, a stoichiometric amount is often employed for better reactivity even when catalysis is possible.)

Answer 2

The product of Sandmeyer's reaction when the primary amine is treated with cuprous bromide are bromomethane and nitrogen.

• $CH_{3}NH_{2}$ ( $NaNo_{2} + HCl$)⇒ $CH_{3} N_{2} Cl$ ($CuBr$)⇒ $CH_{3} Br + N_{2}$
• In Sandmeyer's reaction, primary amine reacts with Sodium nitrite hydrochloric acid under specific temperatures to give $CH_{3} N_{2} Cl$ which is not a stable compound.
• $CH_{3} N_{2} Cl$ further reacts with the Cuprous bromide to form a stable compound $CH_{3} Br$ and liberates $N_{2}$ gas.
• In this reaction, $CH_{3} N_{2} Cl$  formed which is a diazonium salt.

Hence, the product of Sandmeyer's reaction when the primary amine is treated with cuprous bromide are bromomethane and nitrogen.
