Hydrogen Bonding This is a special (stronger) case of dipole-dipole forces. It can exist between a molecule with a hydrogen atom directly attached to an N, O, or F atom and another molecule with a lone pair of electrons on an N, O, or F. The atoms N, O, and F are all very electronegative and very small. When a hydrogen atom is Hydrogen can be cracked out of fossil fuel called hydrocracking and ammonia production mostly for the fertilizer market. Water = H2O is an abundant source for Hydrogen by electrolysis - using photovoltaic s makes this environmentally friendly with no greenhouse gases. You cannot see a pure hydrogen-oxygen flame, because it emits ultraviolet light.

Water has a simple molecular structure. It is composed of one oxygen atom and two hydrogen atoms. Each hydrogen atom is covalently bonded to the oxygen via a shared pair of electrons. Oxygen also has two unshared pairs of electrons. a special kind of bond, called a hydrogen bond, exists between water molecules where the + side of one molecule is attracted to the – end of another molecule, Hydrogen bonds thus help to hold water molecules together. Each water molecule can form a maximum of four hydrogen bonds with other water molecules, and

The Zoom in-office tooth whitening procedure uses the Zoom Advanced Power Chairside Lamp – said to accelerate the bleaching process – to activate the 25 percent hydrogen peroxide whitening. As the hydrogen peroxide is broken down, oxygen enters the enamel and dentin to bleach the stained substances, leaving the structure of the tooth unchanged.

Hydrogen bonding occurs with N,O,F, 3 very electronegative atoms It does this by creating a dipole and since hydrogen is 1g meaning its just a proton, the entire atom is attracted to the dipole so it is very close so the distance is very short for coulumbs law. So that was an intermolecular question which then eventually went to intramolecular
