Q: What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?: Halide only fluoride in normal temperature and pressure may be gaseous;

Q: What is organic matter?: Organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.

Q: Compare the difference between London smoke and Los Angeles photochemical smog: Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.

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: Does Organic Chemistry Study the Performance of Hydrocarbons and Their Derivatives?: Also study the structure and transformation

Q: Peracetic acid is not: A series of compounds produced by the substitution of hydrogen atoms in other molecular or atomic groups as hydrocarbon derivatives, peroxyacetic acid is CH3COOOH, and should be considered

Q: Is the oxygen derivative of the hydrocarbon a non-methane total hydrocarbon?: Since it is a hydrocarbon, it is bound to be a hydrocarbon, and the oxygen derivative of the hydrocarbon is not a hydrocarbon! Therefore, even if the oxygen-containing derivative is volatile again, it is not a non-methane total hydrocarbon

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: 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: 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.
