WebThe effect of hydrogen bonding on the near ultraviolet absorption spectra of some phenols was studied with carbon disulfide as a base. ... These results also support the electrostatic theory of hydrogen bonding. ... CO2 can form hydrogen bonds with water, but its linear shape makes it a nonpolar molecule. This means that carbon dioxide is less ... WebPhenols are a class of alcohols containing a hydroxy group attached to an aromatic ring. The physical properties of the alcohols and phenols are influenced by hydrogen bonding … WebAnd so because of hydrogen bonding, there's interaction between the water molecule and in between the alcohol molecules. So the water molecule is polar. So if you want to think about it in terms of polarity, because of the difference in electronegativity, water is a polar molecule, ethanol is a polar molecule, and like dissolves like. dual bp bratislava
