1. The problem statement, all variables and given/known data Show the product(s) of chlorination (Cl2, FeCl3) of diphenylether 2. Relevant equations None 3. The attempt at a solution My solutions manual shows products with Chlorine in the para position, and then the ortho position, with a note saying (followed by disubstitution) I'm really just looking for some clearing up to this answer. I understand that the oxygen in diphenylether is an ortho/para director, therefore placing Chlorine in the ortho and para position. However, I just assumed this would happen on both phenyl rings. Does it depend on exactly how much Cl2 is provided?
