The intramolecular hydrogen bond in ortho-hydroxy acetophenones

WebPhenol has only one hydrogen on the −OH group available to form hydrogen bonds, so the hydrogen bond is stronger. In toluene, the hydrogen bond is spread over all three hydrogens on the methyl group, so the interaction is weaker overall. Phenol has a higher molecular mass than toluene. None of the above.
