Q:What is the hydrocarbon thing
Hydrocarbons can be divided into: open chain hydrocarbons (carbon atoms in hydrocarbon molecules in open chain) - saturated hydrocarbons - alkanes - unsaturated hydrocarbons - olefins and polyolefins (carbon - carbon double bonds, unstable) - alkynes and (Cyclopentane) - cycloalkene - cycloalkyne aromatic hydrocarbon - monocyclic aromatic hydrocarbon (benzene and its homologues) - fused ring aromatic hydrocarbons (Polycyclic aromatic hydrocarbons and their homologues) - polycyclic aromatic hydrocarbons (naphthalene, anthracene and other condensed ring aromatic hydrocarbons and their homologues) all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water and coal The main ingredients are hydrocarbons
Q:Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?
Hydrocarbons and hydrocarbon derivatives
Q:The functional group of the derivative of the hydrocarbon
Common functional groups are: carbon-carbon double bond, -OH-COOH-CHO-NH2, often react, replace (including halogenation, nitration, sulfonation, esterification, hydrolysis, etc.), addition, elimination, addition polymerization , Organic matter oxidation and reduction, color and so on.
Q:Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?
Although the relative molecular mass of oil is large, but does not belong to the polymer compound, the polymer compound should refer to a chain with a base number n of the material. Nor is it a derivative of saturated hydrocarbons. The oil is a non-saturated tallow fatty acid glyceride, and the fat is a saturated glycerol ester of saturated higher fatty acids. The more the double bond, the lower the boiling point
Q:The problem of system naming of hydrocarbon derivatives
Halogen can be named after the alkane, the other can not
Q:Inorganic chemistry employment direction? Current research direction
Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic matter, which is the oldest branch of chemistry. Inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds. (In addition to carbon dioxide, carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.) Inorganic chemistry is in addition to hydrocarbons and their derivatives, the nature of all elements and their compounds And their reaction to experimental research and theoretical interpretation of science, is the development of the discipline of the earliest branch of a discipline.
Q:Why is red coral red?
Red coral is not absorbed red, so it looks red.
Q:What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
Halide only fluoride in normal temperature and pressure may be gaseous;
Q:Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even
The number of hydrogen atoms in the hydrocarbon must be even.
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.
