How does the polar covalent bonds within the water molecule allow hydrogen bonds to form between water molecules?

Water molecules (H2O) contain a total of eight electrons, six contributed by the oxygen atom and one from each hydrogen atom. One electron pair links each hydrogen atom to the oxygen atom, so a total of two electron pairs are used for linking the three atoms. There are also two free electron pairs not associated with any other atoms. Each of these four electron pairs (two pairs linked, two pairs free) wants to stay as far away as possible from all the other electron pairs. To do this, each electron pair stays at an angle of about 109.5 degrees apart from each other electron pair, measuring the angle from one electron pair through the center of the oxygen atom and on to any of the other electron pairs. Keeping in mind that the shape of the molecule, although affected by all four electron pairs, only shows the links from the oxygen atom to the two hydrogen atoms. The tetrahedral shape forced on the molecule by the four electron pairs does not allow the hydrogen atoms to be 180 degrees apart from each other so the molecule is a "bent" molecule with the hydrogen atoms at a 109.5 degree angle from each other. With the liberal use of imagination, this looks like a boomerang.
The three strongest electronegative atoms are fluorine oxygen, and nitrogen, so they are the only atoms that can work with hydrogen to create a hydrogen bond. Electronegative atoms exert a stronger attractive force than other atoms toward electrons. This pulls the electrons closer to the oxygen atom than to the hydrogen atoms. With the electrons closer to the oxygen atom, the oxygen part of the molecule has a negative charge. With the electrons pulled further away from the hydrogen atoms, the hydrogen side of the molecule has a positive charge. Since opposites attract, the hydrogen side of the molecule is attracted to the oxygen side of other molecules, and of course the oxygen side is also attracted to the hydrogen side of other molecules. This is called a hydrogen bond, and only works with a combination of hydrogen and one of the above listed elements of fluorine, oxygen, and nitrogen.

∙ 9y agoHydrogen bonds hold polar molecules together because of the positive charge. The polar ion generally has a negative charge and bond strongly with hydrogen.

∙ 10y agoPolar molecules have either a positive or negative charge, positives attract negatives so they will attract eachother.

The bonds between hydrogen and oxygen in a water molecule are classified as?
Within the molecule, the bonds are covalent bonds. Between water molecules, they're hydrogen bonds.
What of kind of bonds are found in water molecules?
hydrogen bonding between H2O and covalent bonding within the H2O molecule
What are the bonds between atoms that make up water molecules?
Those are covalent bonds.Bonds between water molecules are defined as polar covalent where there is an unequal distribution of partial charges.
What are the bonds that hold hydrogen and oxygen called?
In water and many other compounds hydrogen and oxygen are held by covalent bonds.Between water molecules and between other polar molecules hydrogen of one molecule and oxygen of a different molecule are held by hydrogen bonds.
Each water molecule is joined to?
Each water molecule forms multiple hydrogen bonds with neighboring water molecules. These bonds are transient and easily and quickly shift among molecules.

What type of bond is in a molecule of water?
Covalent bond between oxygen and hydrogen in water. Intermoleculat hydrogen bond between water molecules.

What is the type of chemical bond within a water molecule?
The two hydrogen molecules and the oxygen molecule in water are joined by covalent bonding where they share the electron.
How many covalent bonds has a hydrogen atom?
None, but the hydrogen molecule has one: H-H A bond takes place between atoms to make molecules.
What type of bond between the atoms forming water molecules?
Hydrogen bonds are the strongest intermolecular force between water molecules, it occurs between a negatively charged oxgen atom of one water molecule and the positively charged hydrogen atom. This is the strongest inter molecular force there is.
What is an example of a molecule with a covalent bond?
H2 Hydrogen gas has one single covalent bond in between the two hydrogen atoms. some other molecules also have the single covalent bonds as HF,HCl,HBr and HI.
