Document Summary

Chapter two: polar covalent bonds; acids and bases. In covalent bonds, electrons are not always shared equally. Fluorine attracts electrons more b/c its more electronegative therefore is partially negative, leaving hydrogen to be partially positive. The ability of an atom in a molecule to attract electrons toward itself. 4. 0-2. 1 = 1. 9 pure covalent polar covalent ionic. Many reactions of organic molecules occur due to bond diploes: Describe a separation of charge in a molecule. Dipole moment of the molecule is the vector sum of all bond dipoles. Need both resonance forms to describe the bonding of this molecule. The bonds form between the 1st and the 2nd carbon and between the. It allows the molecule to become more stable. Sharing of electrons among many atoms (delocalization) stabilizes molecule: delocalized bonding described by a combination of resonance forms is more stable than the bonding described by any individual resonance form. Bond length between single and double bond are equal in length.
