Question

p-Aminophenol on coupling with benzenediazonium chloride in a basic medium gives 4-amino-3-phenylazophenol.

(a) True

(b) False

I had been asked this question in an interview for internship.

This key question is from Diazonium Salts Chemical Reactions topic in portion Amines of Chemistry – Class 12

Answer 1

Right option is (b) False

To explain I would say: As the reaction takes place in a basic medium, the coupling will take place at the ortho position (since para position is already occupied by amino group) with respect to OH group. This results in the compound 4-amino-2-phenylazophenol.
