Question

can you please answer both questions

Devise a synthesis of these compounds starting with three-carbon alkyl halides. Show any necessary reagents and reaction conditions. All carbons must ultimately come from the 3-carbon alkyl halides. Once you have made a new compound you may reuse it without making it again. Butanone Br -OH OH PCL Butanoic acid or CEN N ENHOS
