WebNov 26, 2024 · Hydrogen bonds are formed between a species with a polar X δ- -H δ+ bond and a species with a lone pair (Y δ- ), i.e., X δ- -H δ+ ...Y δ-. The most common species for X are oxygen and nitrogen, and to a lesser extent carbon, fluorine, and sulfur. However, as long as the X-H bond is polar then hydrogen bonding is possible.
WebJan 23, 2024 · The carboxylic acids with up to four carbon atoms will mix with water in any proportion. When you mix the two together, the energy released when the new hydrogen bonds form is much the same as is needed to break the hydrogen bonds in the pure liquids.
