One way to think about this is as an acid-base equilibrium with competition between two acids – H₃O⁺ and the protonated 2-methylpentan-2-ol. If you consult a pKa table§, then you will find that protonated organic alcohols typically have pKa values around -2, while H₃O⁺ has a pKa of -1.7. This means that the protonated alcohol is a slightly …
