... group (the carbonyl) and left others alone (e.g. alkenes). If we want to reduce an alkene or alkyne, we need to use a different kind of hydrogen source – one which is not chemoselective but will add hydrogen across any bond. We want our hydrogen source to be, quite literally, hydrogen (H2). Proble ...
