Which of the following is involved in Sandmeyer's reaction?
Options
- AFerrous salt
- BDiazonium salt
- CAmmonium salt
- DCupromonium salt
Correct answer
B. Diazonium salt
Step-by-step solution
Aryl halides can be prepared by the decomposition of aryl diazonium salts in presence of copper halides solution dissolved in the corresponding halogen acid, the diazo group is replaced by a halogen atom. This reaction is known as Sandmeyer reaction.
