Chemical properties of diazonium salts
Questions
Sandmeyer reaction is better than Gattermann reaction because:
- sandmeyer reaction uses salt of copper while Gattermann reaction uses copper powder.
- only one salt is produced in Sandmeyer reaction while Gattermann reaction produces two salts.
- sandmeyer reaction gives better yield than Gattermann reaction.
- all of the above.
