Water is a polar molecule, meaning it has a positive and negative end. The polarity allows multiple hydrogen bonds to form among adjacent water molecules.The hydrogen bonds attract water molecules to one another, and account for the ability of water molecules to adhere, or stick together, such ...
How are hydrogen bonds formed?Hydrogen:Hydrogen is one of the most prominent gases which is formed at the time of the evolution of the earth. It is not present in molecular form. Hydrogen is the most abundant gas found on the earth's surface....
Hydrogen bonding is a type intermolecular attractive force and is a special class of dipole-dipole interaction. Its dipoles form between hydrogen and either nitrogen, oxygen, or fluorine (these are the nonmetals with the strongest electronegativities). The strong electronegativities of these three ...

We have used density functional theory calculations to investigate how the hydrogen-bond strength is modified when a ligand is bound to a metal using over 60 model systems involving six metals and eight ligands frequently encountered in metalloproteins. We study how the hydrogen-bond geometry and ...

First, water molecules (two atoms of hydrogen and one atom of oxygen joined together) naturally stick to one another, so they clump together in big droplets on the window. The forces that make them do this are called cohesive forces (and the process involved is called cohesion). Second, ...

When submerged in water, the fibers expand because water molecules form hydrogen bonds with individual molecules within each fiber. The water molecules also interfere with weak attractions between adjacent fibers, and the fabric as a whole can lose its strength. In order to avoid ruining your ...
