Silicone can contain CHR groups but does not always, whether this changes its status I don't know.
That is true and may be expressed as aan organo-silicone polymer or a silicone polymer with organic side groups.
The term VOC of volatile organic carbon, restricts itself to organic materials that evaporate into the air; volatile. This would not include coal or limestone; carbonates, since these are solid. It is more about additives such as solvents, although technically, the smell of freshly baked bread is a range of VOC's. That is a good and enjoyable VOC. Perfumes are VOC's and they do more good than bad.
The confusion has to do with word games and redefining words and terms like organic and VOC, to target someone or something. The restaurant cooking the garlic, onions and peppers in olive oil, although releasing volatile organic carbon compounds, gets a pass since they are only after big oil and its related industries; oil and chemicals from oil.
Organic Chemistry, which was my favorite subject in college, is about carbon containing compounds, from solvents like methyl ethyl ketone; MEK, and dimethylformamide; DMF, to organic template materials like DNA. It was about all the various chemicals and reactions needed to make the wide spectrum of carbon products. But the term organic was hijacked and narrowed to mean just natural products, which is only a few chapters in any inclusive Organic Chemistry Book. You can find specialist books that treat this one category; biochemistry.
Physical Chemistry was the original Physics of matter, and is the most inclusive, going beyond just carbon based compounds to discussions of the physics of all chemicals including life. This is the hardest area of Chemistry. I was often behind due to over sleeping this 8AM class, but I could ace the finals. My acing the O-Chem and the P-Chem finals, as an Engineer, and is how I got the recommendation into Grad school, and a nomination into the Chemical Honor Society as a Junior.
My water and hydrogen bonding model for life, to address evolution, is based on the physical bio-organic chemistry of organics, water and hydrogen bonding. I use water as the integrating variable, since it touches everything and is also self binding as liquid water; stable matrix for life. There as 50 times as many water molecules as all the organic molecules combined. This allows a way for the sheer complexity of life and evolution to have a sense of direction, instituted by the water. The DNA double helix is due to water.
The properties of Polymers, which are organic macromolecules, are based on their second bonding forces. Picture a bunch of worms with sticky outer surfaces, lightly connected but wiggling. In the case of liquid water and life, the strongest secondary bonding forces are hydrogen bonding which is dominated by the water. Each water molecule can form up to 4 hydrogen bonds.
Due to the free energy needs of this hydrogen bonding of water; physical chemistry, the rest of the organic have to find their place in the aqueous grid and assume their proper 3-D shapes, that minimize the potential of the secondary bonding of the water. As life evolves, the global water and hydrogen bonding constraint changes via the secondary bonding. However, the molecular of water does not change, but is the same as a billion year ago. Based on the 2nd law of increasing complexity, the organics have all the potential for change, at the primary bonding level, and as complexity increases; evolution is directed by the unchanging primary bonding state of water, which allows for hydrogen bonding.
Hydrogen bonding within water is like a binary switch than can flip between two stable states; polar and covalent, The hydrogen bond does not break but rather flips between the two states, which changes the parameters of the hydrogen bonding. As life evolves, the water feels this, so switches are flipped, but this has no effect on the primary state of water or on the number of hydrogen bonds. However, it does impact the free energy within the still dominate aqueous grid. This moving line; flip switches, become the new goal for the organics; evolution.
The confusion is created by the statistical assumptions in a black box, which make evolution seem impossible, due to more wrong than right happening if we assume random. A small genetic change if progressive may be a subtle positive. But if the genetic change is negative, it can be life threatening. But with water a stable primary bonding bookend, due to its long term chemical stability, and its hydrogen bonding king of the secondary bonding forces within life, no matter the switch settings there is only way to go; evolve the organic toward the endgames of water and the organic influence on its switches; consciousness.
