Water has the property to stick to itself (cohesion) and also with other molecules (adhesion). When water droplets fall on a leaf, the hydrogen bonds present between the molecules of water are more substantial than the intermolecular forces of adhesion between the water molecules and the leaf. ...
The role of hydrogen-bonds playing for electronic properties is studied from the theoretical viewpoint in two kinds of transition-metal (TM) compounds: halogen-bridged mixed-valence TM-complexes (type I) and perovskite-type hole-doped TM-oxides under hydrogen-containing atmosphere (type II). It...
Some covalently bonded hydrides have a hydrogenatombound simultaneously to two separate electronegative atoms, which are then said to be hydrogen bonded. The strongest hydrogen bonds involve the small, highly electronegative atoms offluorine(F), oxygen, andnitrogen. In the bifluoride ion, HF2−, ...

12 Which statement about the properties of water is correct?B A Bonds between hydrogen atoms cause water to have a high specific heat capacity. B The high latent heat of vaporisation of water is due to the presence of hydrogen bonds C The high specific heat capacity of water causes cooling...
Therefore, we should not recommend the use of the Laplacian of the electron density as a criterion for C-H···F-C hydrogen bonds. 展开▼ 机译:卡米纳蒂及其同事已通过实验证明了三氟甲烷与环状分子(环氧乙烷,环丁酮,二恶烷和吡啶)的配合物中C-H···F-C氢键的存在。该研究为B97D / 6-...
Observation of topological hydrogen-bonding domains in physical hydrogel for excellent self-healing and elasticity Physical hydrogels have potential in a range of applications, but can have properties that make these applications challenging. Here, the authors report the development of a hydrogel with sel...
They found that water molecules were strongly confined by hydrogen-bonds in the two ILs. The v(OH) of water can be used as a reliable IR probe for the polarity of ILs. Using FTIR and DFT, Zheng et al. revealed the species changes and hydrogen-bond properties in the 1-butyl-3-...
