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 a stronger bond....
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...

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 high surface tension of water is explained by this property.
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....
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 ...
The energy goes into breaking hydrogen bonds. It takes a lot of energy to make water increase in temperature. The reverse is true too; it takes a lot of energy to lower the temperature of water. Basically, water really doesn't want to change temperature. We're pretty lucky to be made ...
Aromatic hydrocarbons, which are cyclic compounds with conjugated double bonds. Alkenes Unsaturated alkenes are compounds with at least a single double bond in their skeletal structure. The double carbon to carbon bond prevents this hydrocarbon from being bonded with the maximum number of hydrogens. ...
