COMEDK · Chemistry · 25. Haloalkanes and Haloarenes
The reaction \(A r \mathrm{~N}_{2}^{+} \mathrm{Cl}^{-} \stackrel{\mathrm{Cu} / \mathrm{HCl}}{\longrightarrow} \mathrm{ArCl}+\mathrm{N}_{2}+\mathrm{CuCl}\) is called as
- A Sandmeyer reaction
- B Gattermann reaction
- C Claisen reaction
- D Carbylamine reaction
Answer & Solution
Correct Answer
(B) Gattermann reaction
Step-by-step Solution
Detailed explanation
The reaction of an arenediazonium salt with copper powder in the presence of the corresponding halogen acid (HCl or HBr) to replace the diazonium group with a halogen atom is known as the Gattermann reaction. While the Sandmeyer reaction uses copper(I) salts (CuCl or CuBr) as…
