State a new hydrocarbon with molecular formula

Reference no: EM13180528

When 2-fluorobromobenzene is treated with magnesium metal in the presence of anthracene, a new hydrocarbon with molecular formula C20H14 is obtained in low yield. The 13C NMR of this new product shows three peaks in the 120-150 ppm range and one peak at 54 ppm. Propose a structure for this new product consistent with the information presented.
