Document Summary
Polar covalent bond: a bond in which the bonding electrons are attracted somewhat more strongly by one atom than by the other. Intermediate between nonpolar covalent bonds and ionic bonds. Electronegativity (en): the ability of an atom in a molecule to attract the shared electrons in a covalent bond. Electrostatic potential map: portrays the calculated electron distribution in a molecule: electron-rich regions are in red, and electron-poor regions are blue, resultant molecular dipole can be looked at in the following way: Center of mass of all positive charges (nuclei) and all negative charges (electrons) in a molecule.
