When phenol is refluxed with allyl bromide in acetone
solution in the presence of anhydrous potassiym
carbonate a product may be isolated which, on
heating to `200^(@)C` is converted mainly to

When phenol Is heated with ammonia at 300^(@)C in the presence of anhydrous ZnCl_(2) , it is converted into

Aniline is reacted with bromine water and the resulting product is treated with an aqueous solution of sodium nitrite in presence of dilute hydrochloric acid. The compound so formed is converted into. The compound so formed is converted into a tetrafluoroborate which is subsequently heated. The final product is

When phenol (M) is heated with zinc dust, it gives compound 'N' which is the first aromatic compound studied. When compound 'N' is treated with carbon monoxide and hydrogen chloride under high pressure in the presence of anhydrous aluminium chloride and cuprous chloride , it gives compound 'Q'. Identify the compound 'N' and 'Q'.

When phenol is treated with a solution of Br_(2) in carbon disulphide at 0^(@)C , the major product formed is

When phenol reacts with phtalic anhydride in presence of H_2SO_4 and heated and hot raction mixture is pourd in NaOH solution. The product formed is
