If yes, why do we need HCl ?

There are many reactions of diazonium salts. The second one, however, is not one of them. I think to get the benzene ring you have to use H3PO2, hypophosphorus acid.
The first reaction is simple to allow the diazonium salt to go above 5 degrees Celsius in the orginal solution.
