In the given reaction, the product "Z" is - CH ₃ -CH(OH)-CH ₃ Cu / 573 K . oxidation Z

Step-by-step solution

The given reactant is CH ₃ -CH(OH)-CH ₃ , which is propan-2-ol, a secondary alcohol. When vapours of a secondary alcohol are passed over heated copper at 573 K , it undergoes dehydrogenation to form a ketone. CH ₃ -CH(OH)-CH ₃ Cu / 573 K CH ₃ -CO-CH ₃ + H ₂ Thus, the product Z is propanone (acetone), CH ₃ -CO-CH ₃ . Answer: CH ₃ -CO-CH ₃
