Q: What does organic and inorganic mean?: Organic and inorganic machine myself ~ female and male

Q: Simply talk about hydrocarbons: Hydrocarbons in petroleum are abbreviations of hydrocarbons, which are written in the "water" and "water" in "carbon". Hydrocarbons are classified as saturated hydrocarbons and unsaturated hydrocarbons. Petroleum hydrocarbons are mostly saturated hydrocarbons, and unsaturated hydrocarbons such as ethylene, acetylene, etc., generally only in the oil processing process can be obtained.

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: The functional group of the derivative of the hydrocarbon: Yes, the number of carbon after a certain, only to determine the nature of the functional group. This is also the reason for the name of the functional group

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

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: 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.
