in hydration via h20, oxygen is protonated, cant v directly protonate alkene…. in hydration via alcohol alkene is protonated first instead of o why??

In reply to xh z. Thank you for spotting that - putting in my fix queue!

For the last test question, after the alkyl transfer, should the positive charge be on carbon 2 (as you marked) instead of carbon 1?

In reply to SC. Good question. Acid-base reactions are reversible. So certainly, the hydroxyl group could be protonated, but so long as protonation is reversible, and a small percentage of alkene protonation can occur, then the reaction will eventually funnel towards formation of the cyclic product.

In #8, intramolecular reactions, are alkenes always going to act as a “stronger base” than alcohols on the same molecule? Or can both things happen, where alcohols are protonated first before alkenes? I’m thinking oxygen is more electronegative and thus accepts a proton better than a double bond.

In reply to Jayant Kundu. I'm glad you find it useful Jayant. I do recommend going through this site with a textbook and also while being enrolled in a class, as it does help provide structure.
