WebThese labels were derived by considering whether the crystal was racemic or enantiopure (from the space group), its hydrogen bonding graph set and information from the XPac analysis. This showed (Fig. 11.4) that many low energy structures contained the same stack of hydrogen-bonded dimers, and some had the same layers in common. WebNov 13, 2024 · Hydrogen bonding is responsible for ammonia 's remarkably high solubility in water. Many organic (carboxylic) acids form hydrogen-bonded dimers in the solid state. Here the hydrogen bond acceptor is the π electron cloud of a benzene ring. This type of interaction is important in maintaining the shape of proteins.
