If we heat BDC with water then phenol is formed. I was wondering what would happen if we heated dry benzenediazonium chloride. I know that on heating benzenediazonium fluoroborate we obtain fluorobenzene but then it (benzenediazonium fluoroborate) is insoluble in H2O so there is no confusion over there. On the other hand BDC can be obtained in both forms.

  • $\begingroup$ @AdvilSell Thank You. You are right that it will explode. Read it in a few other places as well. However I am surprised that they explode. If you come to know more about , perhaps with more details then please post it up. $\endgroup$ – Nisarg Upadhyaya Feb 18 '19 at 11:11
