The article "Benzene forms hydrogen bonds with water" by S. Suzuki, et al. (14 August., p. 942) represents a major advance in our understanding of their interactions between water and aromatic structures. The authors show that benzene forms hydrogen bonds with water through the π electron system of benzene. Although they did not mention it, their work

Hydrogen bonds, improper hydrogen bonds and dihydrogen bonds
Journal of Molecular Structure: THEOCHEM, 2003Abstract The structures, interaction energies and vibrational spectra of a large number of molecular complexes, formed by binary combination of the covalent hydrides of some of the elements of the first two rows of the periodic table, have been determined by means of ab initio molecular orbital theory at the MP2 level, using the 6-311++G(d,p) basis ...

Hydrogen Bonded Arrays: The Power of Multiple Hydrogen Bonds
Journal of the American Chemical Society, 2012Hydrogen bond interactions in small covalent model compounds (i.e., deprotonated polyhydroxy alcohols) were measured by negative ion photoelectron spectroscopy. The experimentally determined vertical and adiabatic electron detachment energies for (HOCH(2)CH(2))(2)CHO(-)(2a), (HOCH(2)CH(2))(3)CO(-) (3a), and (HOCH(2)CH(2)CH(OH)CH(2))(3)CO(-) (4a)reveal ...

Abstract The concept of the hydrogen bond is a century old but remains youthful because of its vital role in so many branches of science and because of continued advances in experiment, theory and simulation. We discuss the structural and energetic characteristics of normal hydrogen bonds X–H···Y as well as some exceptions to the normal, including ...

My first encounter with H2 was typical for a boy in the age of chemistry sets that had some zing to them. My set, made by A. C. Gilbert Co., contained some powdered zinc. It had no acids, but it taught you to generate them from chemicals it included (for instance HCl from NaHSO4 and NH4Cl), or—the manual said— you could buy a small quantity from your ...
