प्रश्न
The reaction \[\ce{Ar\overset{+}{N2}Cl- ->[Cu/HCl] ArCl + N2 + CuCl}\] is anmed as ______.
विकल्प
Sandmeyer reaction
Gatterman reaction
Claisen reaction
Carbylamine reaction
उत्तर
The reaction \[\ce{Ar\overset{+}{N2}Cl- ->[Cu/HCl] ArCl + N2 + CuCl}\] is anmed as Gatterman reaction.
Explanation:
Diazonium salts react with copper powder and halogen acid to form aryl halide.
Gattermann reaction is a Sandmeyer reaction variant in which \[\ce{Cu}\] powder replaces \[\ce{CuCl}\].
This substitution produces aryl halide more easily and under milder conditions than the Sandmeyer reaction.
