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 …

Clear agreement … Deuterium oxide is used in nuclear magnetic resonance spectroscopy when using water as solvent if the nuclide of interest is hydrogen. This is because the signal from light-water ( H2O) solvent molecules interferes with the signal from the molecule of interest dissolved in it. Deuterium has a different magnetic moment and therefore does not contribute to the H-NMR signal at the hydrogen-1 resonance frequency.
