Hydrogen bonding is the electrostatic attraction that exists between a hydrogen atom and another electronegative atom. Electrostatic attraction represents the development of attraction between two molecules that have different charges. The hydrogen bond model represents a molecule with hydrogen bonds. Example...
Examples of Hydrogen Bonds Hydrogen bonds are found in nucleic acids between base pairs and between water molecules. Hydrogen bonds also form between hydrogen and carbon atoms of different chloroform molecules, between hydrogen and nitrogen atoms of neighboring ammonia molecules, between repeating subunits...
creating a molecule in the process. The new atom, that is in the hydrogen bond, just remains in an electrostatic attraction with that hydrogen atom. Hydrogen bonds are easier to break than covalent or ionic bonds because they do not involve the sharing or transfer of electrons which creates ...
Hydrogen bond has a structural role during the formation of polymers, both synthetic (e.g. nylon) and natural (e.g. cellulose). Hydrogen bonds account for the crystallization and the reinforcement of materials. In aramid fiber, the hydrogen bonds help in stabilizing the linear chains laterally....
Structures of the products have been studied by X-ray diffraction. All the compounds form dimeric units in the solid state. Their common feature is a central core formed by four charge-assisted N (+)–H ()S hydrogen bonds in the form of eight-membered ring with four donors and two ...
British Dictionary definitions for hydrogen bond hydrogen bond noun a weak chemical bond between an electronegative atom, such as fluorine, oxygen, or nitrogen, and a hydrogen atom bound to another electronegative atom. Hydrogen bonds are responsible for the properties of water and many biological mol...
disruptshydrogen bondsbetween water molecules, forming a clathrate-like structure on their surface. The structure is more ordered than free water molecules. The change inentropy(disorder) causes nonpolar molecules to clump together to decrease their exposure to water and thus decrease the entropy of ...

Hydrogen bonds are very common and extremely important in biological systems. They are strong enough to hold substances together but weak enough to break apart and allow chemical changes to take place within the system. Van der Waals forces are yet another type of chemical bond. They are named...
Examples of Chemicals Containing Hydroxide Ion The hydroxide ion formula is very simple with only an oxygen and hydrogen atom and a negative charge on the oxygen. This negative charge allows it to form ionic bonds with other compounds. There are many chemical compounds that form ionic bonds with...
