It forms the most stable carbocation!
A tertiary alcohol dehydrates the most rapid indeed.
We protonate first, then form the carbocation. A tertiary carbocation is very stable, and the rate at which it forms is fast.
You seem a bit confused. When an alcohol is placed in an acidic medium such as HBr, it will protonate and lose the OH group as water.
Primary alcohols goes slowly and do not even form a carbocation !!! Secondary alcohols react fairly quick,,,,,tertiary alcohols react super fast !!!
Hope this helps.
