Plz solve this question with mechanism
Solution-
Explanation & Assumption-
Explanation & Assumption-
- NaNO2+HCl is a very important reagent that can be used for the generation of the diazonium salts and used for further reactions.
- HBr gives the nucleophile (Bromide ions) hence, replace the diazonium salt with a bromine atom.
- AgCl/H2O given the OH- nucleophile and this will be a more dominating nucleophile than Br-. Hence, it replaces that.
- Here, no pyridine will be formed as a clear mechanism is also provided.
