Q:Hydrocarbon and hydrocarbon derivatives system information! The
Hydrocarbon derivatives
Q:The role of aromatic hydrocarbons
Two cases: First, the name of monocyclic aromatic hydrocarbons, usually benzene ring for the mother, alkyl as a substituent. Second, the structure is more complex aromatic hydrocarbons, usually based on the hydrocarbon base, benzene ring as a substituent. Xylene, 2-methyl-3-phenylpentane, diphenylmethane, etc. For the naming of multifunctional compounds, attention is given to the priority order of the functional groups. The priority is preceded by the parent, usually: cations, COOH SO2H, COOR, COCl, CONH2, CN, CHO, CO, OH, SH, NH2, alkynes, alkenes, ethers, X, NO2, etc. [2]
Q:Why is dry ice not organic?
Organic compounds are mainly composed of oxygen, hydrogen, and carbon, and organic matter is the material basis for life.
Q:Why can organic matter be unique in chemical substances? What is the nature of the C atom?
To give a reason, the current production of more economical temperature control is limited.
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:Why does the molecular atom compound do not belong to the life structure
Life structure is composed of CHO as the main element through the covalent bond of the combination of hydrocarbons and their derivatives, and you said the molecular atomic compounds are usually atomic or ionic bond
Q:What is the isomeric structure of oxygen-containing derivatives?
Play the Transformers. As long as the same molecular formula, you can group out how many different structures, there are a number of isomers.
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: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.
Q:Are all carbon compounds all organic?
Not organic matter that is organic compounds. Carbon compounds (carbon monoxide, carbon dioxide, carbonates, metal carbides and other rare carbon compounds excluded) or hydrocarbons and their derivatives in general. Organic matter is the material basis for life.
