The reactions involve bromination, treatment with NaOH, and reaction with SOCl2. The hints provided, including the formation of 2-phenyl-2-propanol from a Grignard reagent and the IR spectral data indicating functional groups, guide us to deduce that compound Z is Benzoyl chloride. This conclusion is supported by the transformation steps and the characteristic IR peaks associated with the compounds."}
