Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
Oxygenated derivatives are: methyl ether, methyl ethyl ether, formaldehyde, ethylene oxide;
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: Why the silicon hydride less, a lot of hydrocarbons. (Why did not you find silicon-based creatures) and why are so many oxides of silicon, little carbon oxides?
You know silane bar, SiH4, this thing will be spontaneous, very unstable
Q: Chemical life network: chemical (inorganic reaction, organic reaction) is equal to the life of life reaction?
Inorganic chemistry is the science of the composition, nature, structure and reaction of inorganic substances. It is the oldest branch of chemistry. All inorganic substances include all chemical elements and their compounds, except for most of the carbon compounds (except for carbon dioxide, Carbon monoxide, carbon disulfide, carbonates and other simple carbon compounds are still inorganic substances, the rest are organic matter.
Q: Are the asphalt and peat kinds of vegetables have heavy metal?
Asphalt is composed of different molecular weight hydrocarbons and non-metallic derivatives of dark brown complex mixture, is a high viscosity organic liquid, was liquid, the surface was black, soluble in carbon disulfide. Asphalt is a waterproof moisture and corrosion of organic cementitious materials. Asphalt can be divided into coal tar pitch, petroleum asphalt and natural asphalt three: Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural asphalt is stored in the ground, and some of the formation of ore or in the crustal surface accumulation. Asphalt is mainly used for coatings, plastics, rubber and other industries and pavement and so on.
Q: Are all carbon compounds all organic?
Of course not Like carbon monoxide is not friends ~ ~ ~ In general, organic matter will contain at least two elements of carbon and hydrogen, but carbon tetrachloride is an exception. Many of the concepts in chemistry, or else there is a special case, or that is limited, can only control the total but can not control the whole. It is very annoying thing oh ~ ~ ~
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: Are hydrocarbons all organic?
The organic matter is an abbreviation of an organic compound and refers to a compound containing a carbon (C) element (a carbon-containing oxide such as CO.CO2 and a carbonate and bicarbonate-containing compound such as CaCO3.NaHCO3, a metal carbide such as CaC2 , Cyanide, etc.), simply say that most of the carbon-containing compounds and their derivatives of all elements and their compounds, while carbonates, carbonates, bicarbonates and other compounds, although the hydrocarbon is inorganic.
Q: Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons
Pro-butylbenzene ethane
Q: Junior high school chemistry knowledge, please explain what is organic compounds, inorganic compounds.
2. Previously, the known organic matter is obtained from animals and plants and other organisms, so this kind of compound is called organic matter. To the 1820s, scientists have used inorganic synthesis of many organic compounds, such as urea, acetic acid, fat, etc., to break the organic matter can only be obtained from the organic concept. However, due to historical and customary reasons, people still use the name of organic matter.
