- 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 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:What are the derivatives of hydrocarbons?
- In addition to the C and H elements, there are also one or more of O, X (halogen), N, S and other elements, such as methanol (CH3OH) learned from junior high school chemistry, (CH3Cl), nitrobenzene (C6H5NO2), and the like, which are mentioned in the previous chapter, are derivatives of hydrocarbons, such as ethanol (C2H5OH), acetic acid (CH3COOH)
- Q:China's largest asphalt production base where
- Asphalt material is divided into asphalt and tar asphalt two categories. Asphalt is divided into natural asphalt and petroleum asphalt, natural asphalt is the oil exudation surface after long-term exposure and evaporation of the residue; oil asphalt is refined processing of residual oil residue, the appropriate process to deal with the product The Tar asphalt is coal, wood and other organic dry distillation processing of the tar after re-processing products. Most of the asphalt used in the project is petroleum asphalt, and petroleum asphalt is a mixture of complex hydrocarbons and their nonmetallic derivatives. Usually the asphalt flash point between 240 ℃ ~ 330 ℃, the ignition point than the flash point of about 3 ℃ ~ 6 ℃, so the construction temperature should be controlled below the flash point.
- Q:What is organic matter? Candle is organic?
- For example: CH4 C2H6O and so 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:Identification of Derivatives of Chemical Hydrocarbons in High School
- Phenol and ferric chloride reaction, aldehyde and copper hydroxide will produce brick red precipitation, and the formation of silver diamine hydroxide silver phase precipitation, and there are aldehydes in formic acid, an aldehyde corresponding to two silver Generation, and formaldehyde can be seen as there are two aldehyde groups, can be generated corresponding to the four silver quality.
- Q:What is the relationship between hydrocarbon and hydrocarbon derivatives?
- Hydrocarbons, which are composed of two elements, carbon and hydrogen, are called hydrocarbons and hydrocarbons. It reacts with chlorine, bromine vapor, oxygen, etc. to produce hydrocarbons.
- Q:Rush! Hydrocarbon and hydrocarbon derivatives system information includes chemical formula, common name, Chinese name and so on
- The system is too difficult to summarize. Too much.
- Q:What is the hydrocarbon thing
- Hydrocarbons can be divided into: open chain hydrocarbons (carbon atoms in hydrocarbon molecules in open chain) - saturated hydrocarbons - alkanes - unsaturated hydrocarbons - olefins and polyolefins (carbon - carbon double bonds, unstable) - alkynes and (Cyclopentane) - cycloalkene - cycloalkyne aromatic hydrocarbon - monocyclic aromatic hydrocarbon (benzene and its homologues) - fused ring aromatic hydrocarbons (Polycyclic aromatic hydrocarbons and their homologues) - polycyclic aromatic hydrocarbons (naphthalene, anthracene and other condensed ring aromatic hydrocarbons and their homologues) all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water and coal The main ingredients are hydrocarbons
