...Covalent bonding includes many kinds of interaction, including σ-bonding, π-bonding, metal to non-metal bonding, agostic interaction, and three-center two-electron bonds.March, J. “Advanced Organic Chemistry” 4th Ed. J. Wiley and Sons, 1991: New York. ISBN 0-471-60180-2.G. L. Miessler and D. A. Tarr “Inorganic Chemistry” 3rd Ed, Pearson/Prentice Hall publisher, ISBN 0-13-035471-6. The term covalent bond dates from 1939.Merriam-Webster - Collegiate Dictionary (2000). The prefix co- means jointly, associated in action, partnered to a lesser degree, etc.; thus a "co-valent bond", essentially, means that the atoms share "valence", such as is discussed in valence bond theory. In the molecule H2, the hydrogen atoms share the two electrons via covalent bonding. Covalency is greatest between atoms of similar electronegativities. Thus, covalent bonding does not necessarily require the two atoms be of the same elements, only that they be of comparable electronegativity. Although covalent bonding entails sharing of electrons, it is not necessarily delocalized. Furthermore, in contrast to electrostatic interactions ("ionic bonds") the strength of covalent bond depends on the angular relation between atoms in polyatomic molecules. Read full entry

covalent bond?
In BF3, we can conclude that
there are three covalent
bonds, but how many of them
are sigma covalent bond and pi
covalent bond?
thank,
detailed explanation would be
more appreciated.

In a covalent bond, what is In an ionic bond we know that
the net charges change and
opposites attract. But in a
covalent bond, they are
sharing electrons. What is
causing the bond attraction
between the two molecules?
Just the sheer fact that they
are sharing electrons?

Neither compound has a full valence shell of electrons, so when they share the electrons, both outer shells are full and the electrons are more stable, or more happy. here is a site that may help explain it a little further: http://www.visionlearning.com/ library/module_viewer.php?mid= 55 |

What is the difference between What is the difference between
a nonpolar covalent bond and a
polar covalent bond?
|

Molecular polarity is dependent on the difference in electronegativity between atoms in a compound and the asymmetry of the compound's structure. For example, water is thought to be polar because of the unequal sharing of its electrons. However, methane is considered non-polar because the carbon shares the hydrogen atoms uniformly. |
