For F324 I've come across loads of questions where phenylamines are reacted with HNO2 and HCl, so you would form a diazonium ion, but how do I know whether to put just the ion or to display the Cl- as well (diazonium salt?) any help would be appreciated.
Secondly, the question i've attached - I understand the product structures, but on the mark scheme the NH becomes NH3+ and the N becomes NH2+. Is this always the case with acid hydrolysis? I thought the NH would become NH2 not NH3+, and the N would become NH not NH2+. It doesn't mention excess acid. Maybe I need to take a break as I'm confusing myself - hope this makes some sense.
