WebDec 12, 2015 · The amide nitrogen technically has a lone pair and thus technically could function as a hydrogen bond acceptor when viewed alone. However, this lone pair is actually significantly delocalised towards the carbonyl bond. If we ignore the two R residues, we could write this the following way: O = C − N − H X − X 2 2 − O − C = N X + − H ... http://www.chem.latech.edu/~deddy/chem121/Alcohols.htm 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. the pacific cigar thailand co. ltd
