Hydrogen bonding General

Metal-hydrogen bonds generally give a high field signal in the 1H NMR spectrum in the region 15—35 r as illustrated by the data on tetranuclear clusters, which is sum-... 

Molecular non-polar molecules or polar molecules dispersion, dipole-dipole, hydrogen bonds generally low (non-polar) intermediate polar very low non-polar very soft soluble in non-polar solvents non-polar formed from symmetrical molecules containing covalent bonds between atoms with small elecbronegativity differences non-polar Brz, GH4, GO2, N2... 

A hydrogen bond of the type we have to consider here (i. e. a non-ionic hydrogen bond) generally involves a neutral, electronegative atom X, such as N or O, offering a lone pmr of electrrms, and a neutral, though moderately polar, short and strong Y-H bond, such as N-H or 0—H, as the electron acceptor ...

A chemical bond is the physical phenomenon responsible for the attractive interactions between atoms that confers stability to di- and polyatomic chemical compounds. There are mainly three kinds of chemical bonds covalent bonds, ionic bonds, and hydrogen bonds. Generally covalent and ionic bonds are often described as strong, whereas hydrogen bonds and van der Waals are generally considered to be weaker.
