Summary: 


For a continuation of our chemistry lesson, class, here we have
a representation of the benzene ring, one of the most important
and reactive of all organic compounds.  
   _____
  //   \\
 //     \\
<         >
 \ _____ /
  \_____/

At each vertex of the hexagon, is a carbon atom, which is quite willing
to bond with almost anything else.  For example, if it bonds with
iron,

   Fe_____Fe
    //   \\
   //     \\
Fe<         >Fe
   \ _____ /
    \_____/
   Fe     Fe

we get a compound already reported on in this forum, the Ferrous
Wheel.

When atoms or other organic radicals attach themselves to adjacent 
vertices of the benzene ring, they are referred to as being in the 
ortho position, 

   _____Md
  //   \\
 //     \\
<         >Md
 \ _____ /
  \_____/

so this example is called orthodocs.

Another possible bonding is found when the same radical attaches 
one vertex away from its mate, 

   _____Md
  //   \\
 //     \\
<         >
 \ _____ /
  \_____/
        Md

as in this example, called paradocs.


And when they bond to opposing vertices, 

 Md_____
  //   \\
 //     \\
<         >
 \ _____ /
  \_____/
        Md

they are said to be in metaphysician.


Johnny, you stay and clean the board.  Class is dismissed.
