FND 300 Lecture Notes - Hydrogen Bond, Thermal Conductivity, Lone Pair
Document Summary
1 electronegative oxygen and 2 hydrogen atoms each water molecule can potentially interact with four others to form an organized 3d intermolecular network. Electrostatic attraction between the positive hydrogen end of the water molecule with the negative lone pair of another water molecule is a weak bond (compared to the intramolecular. Each molecule is hydrogen bonded to approximately 3. 4 other water molecules. Partially ordered since h bonds are constantly being formed and broken up but there are sufficient intermolecular bonding such that the water molecules are still held close to one another kinetic energy is removed. Each water molecule is hydrogen bonded to 4 other molecules with o-o-o bond angles of. 109 , which is very close to that of a tetrahedron. 3-d network that forms takes on a hexagonal configuration when two parallel planes of water is hydrogen bonded to each other.
