    A.  Fig. 2, pg. 633
        1. Straight chains
        2. Rings
        3. Branches
3. Carbon can form many compounds
    A.  Called the “backbone”
4. Polymers   
    A. form when chemical bonds link large numbers of monomers in a repeating pattern
        1.  Monomer- (mono = one)
        *draw the 2 types monomers from fig. 3
