Vetysidos Vätebindning Cellulose fibres tend to form hydrogen bondings, in which the fibres are bound together using so called hydroxyl groups when the water content of the web falls below a certain limit. The hydrogen bondings form a sort of "internal size". The bondings between the fibres are extremely strong, even stronger than the fibres. Producing paper using cellulose fibres is based on hydrogen bondings.
A strong chemical bond formed when two electronegative atoms are joined through a hydrogen atom, either in the same or another molecule. The strongest hydrogen bonds are found in compounds containing fluorine, oxygen or nitrogen.
unusually strong dipole-dipole attractions that occur among molecules in which hydrogen is bonded to a highly electronegative atom.
A weak attractive force that occurs between a hydrogen atom of one molecule and, usually, an oxygen atom of another molecule. It is responsible for holding water molecules together to produce the liquid and solid states.
Strong type of intermolecular dipole-dipole atttraction. Occurs between hydrogen and F, O or N.
weak bonds that form between small molecules (or within macromolecules), specifically involving an atom that has a partial negative charge, especially oxygen in water and in living things, and another atom (such as hydrogen) having a partial positive charge; results in 'sticking together' of molecules
describes an important form of partial valency bonding; occurs between one covalently bounded hydrogen atom to an electronegative element and the lone electron pair of an another electronegative atom; water and liquid acetic acid are typical examples
The interaction of a hydrogen atom with another atom, influencing the physical properties and three-dimensional structure of a chemical substance. Hydrogen bonding generally occurs between atoms of hydrogen and nitrogen, oxygen, or fluorine. An important example of a hydrogen bonding is the formation of the DNA double helix.
