Compound X, C14H12Br2, is optically inactive. On treatment with strong base, X gives hydrocarbon Y, C14H10. Compound Y absorbs 2 equivalents of hydrogen when reduced over a palladium catalyst to give Z (C14H14) and reacts with ozone to give one product, benzoic acid (C7H6O2). Draw the structure of compound Z.
