1.	What is the most suitable pH of the medium for the conduction of coupling reaction of benzenediazonium chloride with phenol?(a) 2(b) 4(c) 7(d) 10The question was asked in an international level competition.My question comes from Diazonium Salts Chemical Reactions topic in portion Amines of Chemistry – Class 12
Answer» Right choice is (b) 4 To elaborate: The coupling reaction with phenol OCCURS in a basic medium of pH value approximately 9 to 10. This is to counter the acidic nature of phenol and as a result produce water (by the COMBINATION of OH^– and H^+) during the reaction.
