Hydrogen bonds occur in other molecules as well as water. Ammonia molecules can also stick together when they are cold. Hydrogen bonding can only happen in molecules that have a permanent dipole (as water does) and that also contain the highly electronegative elements fluorine,oxygen, ornitrogen....
Which compound has the strongest hydrogen bonding between its molecules? Explain dipole-dipole interaction, hydrogen bonds, and van der Waals forces. Give examples also. How are ionic and covalent bonds different from hydrogen bonds? How are hydrogen bonds, ionic bonds and covalent bonds differe...
Both covalent and hydrogen bonds are forms of intermolecular forces. Covalent bonds can occur with most elements on the periodic table, while hydrogen bonds usually occur between a hydrogen atom and an oxygen, nitrogen, or fluorine molecule. Also, hydrogen bonds are only about 1/10 as strong as...
This occurs when two functionalgroups of a molecule can form hydrogen bonds with each other. In order for this to happen, both a hydrogen donoran acceptor must be present within one molecule, and they must be within close proximity of each other in themolecule. For example, intramolecular ...
the hydrogen bond formation between the water molecules provides the attractive force to hold the molecular mass together. Intermolecular hydrogen bonding is responsible for the high boiling point of water because it increases the amount of energy required to break the bonds before boiling can begin....

Water, unlike other liquids, has a disordered network of molecules connected by hydrogen bonds (H-bonds)1. The local structure of water is considered to be responsible for its anomalous properties2. Much work3,4 has been devoted to the search for the connection between the local structure of...
This loss of hair shape can also happen when there’s high humidity, since that just means there’s lots of water in the air – the water keeps breaking the hydrogen bonds and your hair can’t retain its styled shape. Changes in humidity ...
Although hydrogen bonding is commonly described as a form of dipole-dipole attraction, it is now clear that it involves a certain measure of electron-sharing (between the external non-bonding electrons and the hydrogen) as well, so these bonds possess some covalent character. Hydrogen bonds are ...
First, the exposed pure graphene surface (devoid of any catalytic material) attracts polar water molecules and makes hydrogen bonds (one or more hydrogen bonds). During sensing such graphene-adsorbed water complexes transfer very little charge to the active region of the surface, that is, the ...
