Hi, very urgent question and would really appreciate your help even if you are unsure. Thanks for your help the question is attached below. I know that part 1 is dehydration and concentrated phosphoric acid but am not sure about step 2 and step 3. Thanks
You can go via an oxirane (epoxide) using a peroxyacid and then hydrolyse it ...
or you can do this directly with potassium manganate(VII) (actually via a complex)
or more exotically with Osmium tetroxide
