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 does organic and inorganic mean?: [Inorganic] inorganic is inorganic compounds referred to, usually refers to non-carbon compounds. A small number of carbon-containing compounds, such as carbon monoxide, carbon dioxide, carbonates, cyanides, etc. are also inorganic. Inorganic materials can be divided into oxides, acids, alkalis, salts and so on. Organic compounds Definitions Organic compounds usually refer to carbon-containing compounds, or hydrocarbons, and their derivatives, are collectively referred to as organic compounds.

Q: What is the difference between crude oil and asphalt?: Asphalt is the residue of crude oil

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: Are there two derivatives of equivalent hydrogen?: You give the scope is too broad, at least to set in what kind of functional group range ah.

Q: Are hydrocarbons all organic?: A series of compounds with similar structures and different molecular composition of one or several "CH2" radicals are called the same series, and each member in the same series is called homologous, and the chemical properties of homologues are similar due to their similar structure. Their physical properties, often with the increase in molecular weight and regular changes.

Q: Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?: The heterocyclic compound is an organic compound containing a heterocyclic structure in its molecule. The atoms that make up the ring contain at least one heteroatom in addition to carbon atoms. The heteroatoms include oxygen, sulfur, nitrogen and the like. Theoretically, the heterocyclic compound can be regarded as a derivative of benzene, that is, one or more CH in the benzene ring is replaced by a heteroatom. The heterocyclic compound may be in parallel with the benzene ring to form a fused ring heterocyclic compound.

Q: Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even: Other hydrocarbon derivatives are not necessarily, such as halogenated hydrocarbons containing odd halogen molecules, containing an odd number of N atoms containing C, H. O, N four elements of the compound, their number of hydrogen atoms are odd.

Q: Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?: Is a hydrocarbon derivative.

Q: How the most primitive life on earth is produced under what conditions: The most primitive creatures on earth are actually RNA, which is pulled earlier than any prokaryotic cells, and the eukaryotic cells are advanced, in short, the chemical reaction in the environment at that time.
