- Explain why 92% of 2,4-pentanedione exists as the enol tautomer in hexane but only 15% of this compound exists as the enol tautomer in water. The enol tautomer can form hydrogen bonds both with hexane and water, but the keto tautomer can form hydrogen bonds with water only. Neither the keto nor the enol tautomer can form hydrogen bonds with hexane, but the keto tautomer can form a hydrogen bond with water, which stabilizes it. The keto tautomer can form hydrogen bonds both with hexane and water, but the enol tautomer can form hydrogen bonds with water only. Neither the keto nor the enol tautomer can form hydrogen bonds with hexane, but the enol tautomer can form an intramolecular hydrogen bond, which stabilizes it.arrow_forwardDraw a mechanism of a reversible reaction of acetophenone and strong acid (H-A) to form a protonated acetophenone and a weak base. Draw all the electron pairs of the molecules and the arrows. Predict 1H NMR spectra of acetophenone and the protonated acetophenone.arrow_forwardIn addition to α cleavage, some aldehydes and ketones undergo the McLafferty rearrangement. In the McLafferty rearrangement, a hydrogen on a carbon three atoms from the C=O is transferred to the carbonyl oxygen and a carbon–carbon bond is broken. This process forms an alkene and the radical cation derived from an enol, which appears as a fragment in the mass spectrum.a.Draw the products formed from the McLafferty rearrangement of 1phenylpentan-1-one, and identify the fragment that results in the given mass spectrum.arrow_forward
