A hydrogen bond is a special type of dipole-dipole force that exists between an electronegative atom and a hydrogen atom bonded to another electronegative atom. This type of force always involves a hydrogen atom and the energy of this attraction is close to that of weak covalent bonds (155 kJ/mol), thus the name - Hydrogen Bonding. These attractions can occur between molecules (intermolecularly), or within different parts of a single molecule (intramolecularly).[2] The hydrogen bond is a very strong fixed dipole-dipole van der Waals-Keesom force, but weaker than covalent, ionic and metallic bonds. The hydrogen bond is somewhere between a covalent bond and an electrostatic intermolecular attraction.
Hydrogen bonds emerge from water's polar nature. Because oxygen is more electronegative than the hydrogens, it pulls electrons away disproportionally. This makes oxygen slightly negative while the hydrogens are slightly positive. Water is also a "bent" molecule which means the hydrogens hang off the oxygen at angles giving it a sort of "L" shape. Because of the shape and the slightly positive and negative sides, water is an overall polar molecule.
When water molecules come into contact with one another, the polar molecules will interact based on their positive and negative ends. The slightly negative oxygen of one molecule will pull in any positive hydrogens (four molecules at the most) of another molecule, and the hydrogens also pull in the oxygens. This attraction - bond - between the oxygen and the hydrogen is the hydrogen bond.
Occurs whenever a covalently bonded hydrogen is slightly positive and is attracted to a negatively charged atom some distance away.
What part of phospholipids form hydrogen bonds with
No, while some organic compounds can form hydrogen bonds, these bonds are not inherently organic. Hydrogen bonds occur where hydrogen is bonded to a highly electronegative element such as oxygen or nitrogen. Organic compounds must contain carbon, which is not related to hydrogen bonding.
If you are mentioning about sticking two hydrogen atoms with one oxygen atom, then it's water. Other than that, oxygen and hydrogen are not together, unless they are water, hydrogen peroxide, or some other compound with an -OH group. In such compounds the hydrogen and oxygen are held together by covalent bonds, the sharing of electrons.
Hydrogen Bonds.(Hydrogen bonding is another term for the dipole-dipole attractions between H2O molecules.) A Hydrogen bond is between a H atom in one molecule and either a O, N, or F atom in another.
Water molecules form covalent bonds, because they are non-metal compounds. If you mean the bonds within the water molecules themselves, they are Hydrogen bonds.
Hydrogen bonds occur between polar molecules such as water.
Hydrogen bonds occur between polar molecules when hydrogen is linked to nitrogen, phosphorous or fluorine.
These are hydrogen bonds between water molecules.
The intermolecular force that hold together adjacent water molecules are hydrogen bonds. Hydrogen bonds are the strongest type of intermolecular forces, but it is still relatively weak compared to ionic and covalent bonds. Hydrogen bonds occur because of the large difference between hydrogen atoms and the highly electronegative atoms such as F, N and O.
Intermolecular bonds of water molecules are hydrogen bonds.
Water molecules are bonded together using hydrogen bonds. Hydrogen bonds occur when positive and negative charged parts of the molecules are attracted to the opposite charge in other molecules.
The bond between water molecules is known as a hydrogen bond.
Hydrogen bonds are INTER-molecular polar forces, not INTRA-molecular bonds.More on chemical bonds, cf. 'Related links', just below this answer.
These are termed to be 'covalent bonds'.
Hydrogen bonds
Water is composed of molecular bonds, but forms hydrogen bonds with other water molecules. Hydrogen bonds are not actual bonds, but they cause an attraction between the water molecules, which is why water is adhesive.
"Individual hydrogen bonds are weak and easily broken; however, they occur in very large numbers in water and in organic polymers, creating a major force in combination. Hydrogen bonds are also responsible for zipping together the DNA double helix." -lumenlearning
