Give only the equation for the synthesis of the fluorobenzene from benzene diazonium chloride.

The equation for the synthesis of the fluorobenzene from benzene diazonium chloride is as follows: When an aqueous solution of diazonium salt is treated with fluoroboric acid HBF 4 , diazonium fluoroborate gets precipitated. It is filtered and dried. When dry diazonium fluoroborate is heated, it composes of aryl fluoride and boron trifluoride. A r N 2 + Cl - + HBF 4 → ArN 2 + BF 4 - + HCl Diazonium fluoroborate Ar - N + ≡ NBF 4 → ∆ Ar - F + N 2 + BF 3 Aryl fluoride
