- Q:Is steel not organic synthetic material?
- Steel is a mixture, the vast majority of elemental iron, also contains other elements, carbon is mixed in the inside, and did not constitute a compound.
- Q:Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not
- Should be able to ah and bromine water addition reaction and fade:
- Q:What are the gaseous states of the oxygen-containing derivatives of the hydrocarbons under the standard conditions?
- Nitrogen derivatives are; dimethylamine;
- 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:Ionic compounds, covalent compounds, electrolytes, non-electrolytes, which are both compounds and inorganic compounds
- An ionic compound consisting of a cation and an anion. Active metals (such as sodium, potassium, calcium, magnesium, etc.) and active non-metallic (such as fluorine, chlorine, oxygen, sulfur, etc.) when the combination of active metal loss of electrons to form positively charged cations (such as Na +, K +, Ca2 + (Such as F-, Cl-, O2-, S2-, etc.), cations and anions are formed by electrostatic interactions to form ionic compounds. For example, sodium chloride is an ionic compound consisting of positively charged sodium ions (Na +) and negatively charged chloride ions (Cl-). Many bases (such as NaOH, KOH, Ba (OH) 2, etc.) and salts (such as CaCl2, KNO3, CuSO4, etc.) are ionic compounds. The total number of positive charges in the cationic compound is equal to the total number of negative charges carried by the anion, and the whole compound is electrically neutral. Most ionic compounds can not be conductive in solid (or crystalline), while their aqueous or molten state can be conductive. The ionic compounds generally have a higher melting point and higher boiling point, higher hardness, crisp and difficult to compress, and the highly volatile ionic compounds are linked by ionic bonds, without independent structures, such as sodium chloride.
- Q:What is the relationship between hydrocarbon and hydrocarbon derivatives?
- The hydrocarbon is the parent of the organic compound, and the other various organic compounds can be regarded as derivatives of one or more hydrogen atoms in the hydrocarbon molecule being replaced by atoms or radicals of other elements.
- Q:What is a derivative of a hydrocarbon? What is an aromatic hydrocarbon derivative?
- Hydrocarbon derivatives include derivatives of linear and aromatic hydrocarbons such as chloroethane bromopropane bromobenzene
- Q:Are all carbon compounds all organic?
- Of course not Like carbon monoxide is not friends ~ ~ ~ In general, organic matter will contain at least two elements of carbon and hydrogen, but carbon tetrachloride is an exception. Many of the concepts in chemistry, or else there is a special case, or that is limited, can only control the total but can not control the whole. It is very annoying thing oh ~ ~ ~
- Q:Sodium can be used to identify derivatives of hydrocarbons
- A compound in which a hydroxyl group is directly attached to a carbon atom in a hydrocarbon group or a benzene ring side chain is called an alcohol.
- 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?
- You know silane bar, SiH4, this thing will be spontaneous, very unstable
