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?: Silicon-based organic matter, oxidized to form silica, this thing is hard, very high melting point of atomic crystals, but the existence of solid on Earth

Q: Such as the problem, and how, how to squeeze methane into liquid, or how to squeeze into the liquid gas? It is still very difficult ... there is a dangerous thing .... (this is not important) high reward: (3) polyethylene (2) is not, is a hydrocarbon derivative, there are C, H, O elements (3) polyethylene material (polyethylene material non-stick pan) (4) oil and oil produced gasoline is liquid , The general organic polymer materials can be burned

Q: Will AsH3 (arsenic trioxide) is organic or inorganic: Organic matter refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.

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: How to do it? Solve Inorganic Chemistry: Inorganic chemistry is one of the earliest disciplines in the development of chemical science. It undertakes a major task of studying the composition, structure, properties and reactions of all elements and elements (except hydrocarbons and derivatives). The current development of inorganic chemistry has two distinct trends, that is, in the breadth of the broadening and depth of the advance. It is the three pillars of modern civilization

Q: Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?: No, aldehyde is functional group, must be aldehyde for the mother. In addition, when the aldehyde group is a substituent, it is named as a formyl group.

Q: What are the characteristics of organic compounds?: Organic compounds are usually referred to as carbon-containing compounds, or hydrocarbon-containing compounds and their derivatives are collectively referred to as organic matter. Organic compounds are generally insoluble in water and soluble in organic solvents with lower melting points. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects, and there are many kinds of organic compounds, which can be divided into two major categories of hydrocarbon and hydrocarbon derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.

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: 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.

Q: Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not: As long as carbon and carbon double bonds and three hydrocarbons can be hydrocarbons
