MD. Descriptive Chemical Compounds

Chemists have developed classifications of some of the more common types of chemical compounds:

1. Organic (contain carbon, and usually hydrogen) [These could be denoted MM<MEC; MM<(MEC + MEH)]

2. Coordination compounds

3. Main group compounds (elements from columns 1, 2, 1nd 13-8, and sometimes 3 and 12)

4. Transmission metal compounds (elements from columns 4 through 11)

5. Organometallic compounds (metals combined with C and H)

6. Oxides (contain O) [Could be denoted MM<MEO]

Note that these classes overlap. Classes 3 and 4 need to be linked to the appropriate MG classes [see MG. Groups of Elements].

Other classes of particular compounds should be considered. Note that chlorides, hydrates, and silicates could be designated by MM< and the notation for chlorine, water, and silicon.

The classes above could be further subdivided, perhaps using linked notation. Organic compounds can be subdivided into those which feature bonds between carbon and a metal, and those which feature bonds between carbon and a phosphorus.
