Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?: Hydrocarbon derivatives of oxygen in the standard conditions are gaseous formaldehyde.

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: Organic organic compounds are organic matter?: Organic polymer compounds are organic matter

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: Artemisinin is not a derivative of hydrocarbons: Artemisinin is a colorless needle-like crystal obtained from the compound inflorescences Artemisia annua L., which is (3R, 5aS, 6R, 8aS, 9R, 12S, 12aR ) - octahydro-3,6,9-trimethyl-3,12-oxo-12H-pyran [4,3-j] -1,2-benzodiazepine-10 (3H) -one. Molecular formula for the C15H22O5.

Q: What is the aromatic hydrocarbon .. what is the derivative of the aromatic hydrocarbon: Aromatic hydrocarbons referred to as "aromatic hydrocarbons", refers to the molecule containing benzene ring structure of the hydrocarbons. Is a closed chain.

Q: What is organic matter? Candle is organic?: For example: CH4 C2H6O and so are organic matter

Q: Is grease a polymer compound? Is it a derivative of saturated hydrocarbons?: Grease is not a polymer, a hydrocarbon (not necessarily a saturated hydrocarbon) derivative,

Q: Why can organic matter be unique in chemical substances? What is the nature of the C atom?: Silicon compounds can also be made like this. However, for silicon-based organisms, the appropriate temperature of silicon-based enzymes is probably too high, the earth is too cold for them.

Q: Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?: Artemisinin is relatively stable, is relative to other organic peroxide in terms of, in general, most of the organic peroxide instability, heating easily decomposed, and some even easy to burn the explosion, such as dibenzoyl peroxide, but crystal cyan Artemisinin heating to the melting point does not break down, has been considered stable.
