  2. An atom which isn't in any rings and isn't an Oxygen.
    		3.
    		 
  3. Two atoms bonded by a non-ring bond.
    		4.
    		 
  4. An aromatic atom single-bonded to any halogen.
    		5.
    		 
  5. An atom that is an Oxygen or a Nitrogen (aliphatic or aromatic) , with at least one hydrogen attached and in a five-membered ring.
    		6.
