    a.) Carbon can make a total of 4 bonds.

    Carbon can bond with itself to form lattices and other structures like rings and chains.

    Carbon form a tetrahedral shape. If you have 4 different substituents bonded to carbon, then you will get a chrial carbon. With a chiral carbon, you can form two types called D and L. Many enzymes can differentiate between these two types by shape. You can have D and L amino acids and D and L sugars. This gives a very large possibility of molecules that you can get.

    b.) Greenhouse effect deals with a compound called a chloroflourocarbon (CFC). This molecule is also a tetrahedral, but not chrial.

    When CFC is radiated with UV light, it breaks down to a free radical Cl.

    When radical Cl attacks ozone (O3), you get a free radical reaction.

    See reaction below:

    In 1974, Mario Molina, now at the Massachusetts Institute of Technology, and F. Sherwood Rowland, at the University of California, Irvine, showed that there was a threat to the ozone layer from chlorofluorocarbons, CFCs. They showed that the CFC molecules would almost all reach the stratosphere where they would liberate chlorine atoms that would then destroy ozone in a catalytic reaction similar to that involving NO(g).

    UV Radiant Energy

    CCl3F(g) ---> CCl2F(g) + Cl(g)

    Cl(g) + O3(g) ---> ClO(g) + O2(g)

    ClO(g) + O(g) ---> Cl(g) + O2(g)

    Cl catalyst

    net reaction O3(g) + O(g) ------> 2O2(g)

    c.) I need a structure to look at.

    good luck.
