Document Summary
Chapter 6: chemistry of water, chemistry in water. Water molecs have 2 polar covalent bonds at an angle of 104* (degrees) to each other. The net result is that the molec has a dipole acing in the direction that bisects the h-o-h angle. The debye (d) is the unit for the dipole moment, mu: The influence of symmetry on the polarity of molecs with 2 and 3 bonds: Polar molecs align themselves so that the + end of one molec is oriented toward the - end of an adjacent molec. This type of intermolecular force is called a dipole-dipole force https://onedrive. live. com/edit. aspx/documents/chemistry?cid=4612573e81e7633b&id=documents&wd=target%28september. one%7cfa2c53b9-0d 1/10. Unexpectedly high boiling points of polar molecs of certain hydrogen components indicate stronger intermolecular forces than predicted by dipole-dipole interactions. Contributions to the strength of h-bonding between h2o molecs: A hydrogen atoms has only 1 e-, which, when localized in the bond, leaves + charged h nucleus rather than exposed to adjacent molecs.
