Hi everyone,
I am unclear on protecting groups. In the book it says that you can use
isobutylene to protect the hydroxyl group of a primary alcohol while
another reaction is carried out on some other part of the molecule. I
don't really understand what this means. Can anyone explain?
Thanks,
Julie S.
