A Carbonyl compound X when reacted with Methyl magnesium bromide followed by hydrolysis gave product Y . When Y is heated with Cu at 573 ~K , it gave Z (2- Methylbut-2-ene) as one of the products. Identify X .

Step-by-step solution

The reaction of a carbonyl compound X with CH ₃ MgBr followed by hydrolysis yields an alcohol Y . Heating alcohol Y with Cu at 573 ~K is a dehydrogenation reaction for primary and secondary alcohols, or a dehydration reaction for tertiary alcohols. Since the product Z is 2-methylbut-2-ene, which is an alkene, the reaction is a dehydration of a tertiary alcohol. The structure of 2-methylbut-2-ene is CH ₃- C ( CH ₃)= CH - CH ₃ . The tertiary alcohol Y that dehydrates to form 2-methylbut-2-ene is 2-methylbutan-2-ol, w
