I'll skip the preparation part which involves 9 steps and move on to the reactions as I have already gotten the preparation in my head and am now struggling with the reactions. I'll leave out the equations as i can't draw benzene rings here.
1) Phenylamines which are weak bases react with strong acids to form salts where the excess of H+ ions shifts the equilibrium to the right.
2) Phenylamines react with copper (II) ions to form complex ions.
3) Phenylamines reacts with nitrous acid at temperatures above 5 degrees celcius to produce phenol.
The nitrous acid is prepared by mixing ice cold solution of sodium nitrite with dilute hydrochloric acid. Ice bath is used to make sure the temperature is lower than 5 degrees celcius.
Below 5 degrees celcius aromatic amines react with nitrous acid to form diazonium compounds.
Now moving on to Diazonium compounds and soon I'll be done with paracetamol as well. ^_^
