Q:Why the silicon hydride less, a lot of hydrocarbons.
Silicon oxide than carbon, because the outermost layer of silicon has three levels ah, (SiO, SiO2, Si2O6) silicon less organic matter, the front also said that the organic instability of silicon
Q:What are the derivatives of hydrocarbons?
Halogenated hydrocarbons, alcohols
Q:What is the difference between an aromatic compound and a hydrocarbon derivative?
The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.
Q:What is organic matter? Candle is organic?
Organic matter refers to the addition: carbon, carbon monoxide, carbon dioxide, carbonated and carbonate carbon compounds
Q:Simply talk about hydrocarbons
Hydrocarbons in petroleum are abbreviations of hydrocarbons, which are written in the "water" and "water" in "carbon". Hydrocarbons are classified as saturated hydrocarbons and unsaturated hydrocarbons. Petroleum hydrocarbons are mostly saturated hydrocarbons, and unsaturated hydrocarbons such as ethylene, acetylene, etc., generally only in the oil processing process can be obtained.
Q:Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?
Should be a hydroxy compound.
Q:What are the oxygen consumption of the oxygen-containing derivatives of the mass hydrocarbons?
For this comparison, you can see the experimental formula of this material, a C corresponds to an oxygen, 4 H corresponds to an oxygen, the experimental consumption of oxygen up, then under the same quality conditions, the greater the oxygen consumption of this material
Q:Why not ah?
A series of compounds in which a hydrogen atom in a hydrocarbon molecule is replaced by another atom or radical is called a derivative of a hydrocarbon
Q:Why is the chemical name in the uncommon word so much?
The most basic hydrogen prefix plus a sound next to tell you that the elements of the common element of the standard situation is the same kind of gas bromide tellurium metal next to the word next to the sound next to no matter how much the child knows that this law will be recited next to the next Periodic table down to know the elements of the material highlights a good note
Q:How the most primitive life on earth is produced under what conditions
These macromolecules are not in the modern sense of the protein and nucleic acid polymer, but a variety of amino acids, nucleosides, phosphoric acid, carbohydrates and some other small molecules of the disorder of the polymer, when the nucleoside and phosphoric acid composition of nucleoside Acid, and gradually form a nucleotide chain, the formation of these nucleotide chain of the amino acid on the formation of the field of binding force, and then assembled peptide chain. Or by the combination of a variety of amino acids into peptide chain formed by the force field on the surrounding nucleus formation field binding effect, and then assembled the nucleotide chain, with the formation of peptide chain and nucleotide chain longer and longer , The molecular weight is growing, and ultimately the formation of nucleic acids and proteins, nucleic acid and protein formation is the product of interaction with each other, is generated at the same time.
