Organic Chemistry Problem
« on: January 31, 2020, 09:00:20 PM »
Can someone explain WHY my mechanism doesn't work and SHOW me the proper mechanism for the answer. I asked this quest. before but the answers weren't very good.

Yes, I know it's an elimination. I want to know WHY it's an elimination and not my way and HOW the elimination occurs. Because I don't understand it and i'll actually need an explanation to gain an understanding.

Is it because it's not diluted acid and the acid protonates the oxygen twice, forming a water leaving group?

But then where do the electrons for the elimination come from if the water takes two when leaving, leaving behind a cation?

From the H+ that is also lost, leaving behind the electron pair.

Check out the book by Jakob Fredlos - has just enough details!

Not quite but almost. Since its tertiary alcohol it will likely go  through carbocation rather than single step
