Can phenol hydrogen bond
WebPhenol ethers, similarly to regular ethers, are less hydrophilic than its precursors, phenols and alcohols, both of which can donate and accept hydrogen bonds. Phenol ethers, however, are still able to accept hydrogen bonds through the ethereal oxygen, allowing for its slight solubility in polar solvents. WebNov 14, 2024 · The boiling point of phenol are higher than the boiling point of aliphatic alcohol with similar molecular weight because of the stronger intermolecular hydrogen bonding in phenol. Intramolecular hydrogen bonding is found if phenol contains an ortho substituent which can accept hydrogen bond.
