Convert 2-butene to butanone

Answer 1

Hi Twiza N.,

You move one hydrogen across the double bond, take the other on the same carbon away, and put a double bonded oxygen on it. Same as elephant in a refrigerator, etc.

But if you were asking as a chemical reaction sequence, you COULD hydrohalogenate the double bond (with HI or HBr), nucleophilic substitute the halide for -OH, then oxidize with hot potassium dichromate to the ketone. You could have looked this up on Google as "reactions of alkenes", then followed through a reaction sequence. It's useful to have a little background of functional groups, so you know what's possible! Hopefully you're picking that up in your course??
