WebSep 16, 2015 · Any lone electron pairs present on the oxygen or nitrogen in the carbonyl, ether, the hydroxyl, the amino, the imino, and the nitrile groups above are hydrogen-bond accepting, while the hydrogens on the hydroxyl, amino, and imino groups are hydrogen-bond donating. That means these parts of these functional groups count: ketone ( C=O) WebJul 13, 2024 · In ice, the hydrogen bonds cause the formation of cavities in the ice, lowering the density of the solid. In liquid water, the hydrogen bonds persist, and are transiently formed on a time scale of ~nano seconds, generating small short-lived clusters of "ice" in liquid water. Hydrogen bonds are present over a wide temperature range.

WebPhenol is quite a weak acid (pKa ~10) so it's likely phenoxide would react with a hydrogen ion or water if given the chance. But besides that, the whole point of this video was to show there is partial double bond character in that C-O bond due to the resonance structures Jay drew. Resonance does imply a certain amount of stability.
