Q: Is carbon monoxide an organic gas?: The organic compound contains carbon, hydrogen, oxygen, nitrogen and other elements, a few also contain sulfur, phosphorus, halogen, etc. Any kind of organic compounds, its molecular composition contains carbon, the vast majority also contains hydrogen Elements. Since the hydrogen atoms of the organic compound molecules can be replaced by other atoms or radicals, resulting in a lot of other organic compounds, so modern people generally believe that hydrocarbons and their derivatives known as organic compounds, referred to as organic matter.

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: 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: Identification of Derivatives of Chemical Hydrocarbons in High School: Derivatives have gone, and give a specific range Well

Q: The role of aromatic hydrocarbons: Aromatic hydrocarbons referred to as "aromatic hydrocarbons", usually refers to the molecule containing benzene ring structure of the hydrocarbons. Is a closed-chain type. With the basic structure of the benzene ring, the history of the early discovery of such compounds have more aromatic flavor, so called these Hydrocarbons are aromatic hydrocarbons, and hydrocarbons that are later found to have no aromatic flavor are also commonly used in this way, such as benzene, naphthalene, etc. The homology of benzene is CnH2n-6 (n≥6).

Q: What are the inorganic compounds: Hydrocarbons and their derivatives.

Q: Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?: Halogen can be named after the alkane, the other can not

Q: What is the difference between hot and cold asphalt?: I only heard the warm mix of asphalt. The How is cold asphalt defined? How much is it cool?

Q: Organic chemistry studies the performance of hydrocarbons and their derivatives, either right or wrong: Correct

Q: Such as the title, the personal feeling of chemical transliteration of Chinese transliteration can be done so easy to write, weird name in addition to keep the high point, no good, but rather affect the people's understanding of medicine and memory, contrary to the text to facilitate the exchange of memory Original intention: China's chemical name may be the best of both Latin and English
