CHM-235  Organic Chemistry I



Course Description:    Rigorous introduction to the chemistry of carbon-containing compounds.  Reaction mechanisms and recent methods of synthesis emphasized.
Prerequisites:    CHM152 and CHM152LL; or CHM154 and CHM154LL.



Course Materials:      


Here is a link for molecular model kits.

          This kit has orbital paddles.

          There are a few different versions of the Molecular Visions Organic Set (Kit 1, 1A, or 2A).
          These sets are cheaper (~$14.00) but do not have orbital paddles.

As with all purchases, shop around.  If you find another good website, let me know.

Hybrid Orbitals    A couple of key points to remember:
    1 - If you add n atomic orbitals, you'll end up with n hybrid orbitals.
    2 - The hybrid orbitals formed will point as far apart as possible.
    3 - Remember that in the case of sp2 and sp hybrids there are unhybridized p-orbitals remaining.


For some alternate depictions of atomic orbitals, there are a many well-constructed websites.  Below are a few URL's you can check out.  I tried to stick to the less elaborate sites so that they could run on most computers.

Electron Motion  Why worry about orbitals and electron motion in the first place.

http://micro.magnet.fsu.edu/electromag/java/atomicorbitals/     This site shows images of s, p , d, and f atomic orbitals.  You can view them individually or several at a time.  Keep in mind that we will deal mainly with hybridization of just the s and p atomic orbitals.  Take a look at the f-orbitals just for fun.

http://www.orbitals.com/orb    This website has images of various atomic orbitals, but not just s, p , d, and f orbitals.  It even shows images of more complicated orbitals.

http://www.towson.edu/~ladon/carbon.html    This is a tutorial on the electron configurations in carbon atoms and it also deals with hybridized orbitals.

             hundreds of satellites in orbit around Earth.
