Q:Is polyethylene a derivative of hydrocarbons?
No, the derivative of the hydrocarbon is an element other than c.H
Q:What is "organic" and "inorganic" in chemistry?
The definition of organic matter usually refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
Q:Why does toluene not belong to the derivatives of hydrocarbons?
Hydrocarbon: sound tīng, is composed of two elements of carbon and hydrogen organic compounds known as hydrocarbons, also known as hydrocarbons. It reacts with chlorine, bromine, oxygen and other hydrocarbons to produce derivatives of hydrocarbons. Such as methane and chlorine in the light conditions of reaction to produce methyl chloride, dichloromethane, chloroform and chloroform (carbon tetrachloride) and other derivatives. The concept of derivatives is hydrocarbon and chlorine, bromine, oxygen and other reaction products. While toluene is not methyl and benzene, she is a whole noun is aromatic. Also known as aromatic hydrocarbons. Generally have one or more six-ring (benzene ring) with a special structure. The simplest aromatic hydrocarbons are benzene, toluene, xylene. There is also naphthenes. As the name suggests it is a ring structure. The most common is the five carbon atoms or six carbon atoms of the ring, the former called cyclopentane, which is called cyclohexane. The molecular formula of the cycloalkane is of the formula CnH2n. Cycloalkane is also called cycloalkane hydrocarbons. And alkanes. Is a carbon atom between the single bond phase chain hydrocarbon. Since the number of atoms that make up the hydrocarbon and hydrogen is different, the result is that the petroleum contains hydrocarbon molecules with large and small differences. Alkanes are named according to the carbon atoms and numbers contained in the molecule, and the number of carbon atoms is less than 10, from 1 to 10, followed by a, B, C, D, E, G, Alkane to say that the number of carbon atoms in more than 11, with the number that thank you to adopt
Q:High school chemical hydrocarbons with hydrocarbon derivatives with water solubility
Hydrocarbons, halogenated hydrocarbons, esters are difficult to dissolve in water. Hydrocarbons, esters are denser than water, and the density of halogenated hydrocarbons is generally greater than that of water. Hydrocarbon derivatives containing hydroxyl, amino or aldehyde groups such as alcohols, phenols, aldehydes, carboxylic acids, sulfonic acids and amines are soluble in water, And the shorter the solubility of the carbon chain, the greater the solubility of the carbon chain increases, until the same number of carbon atoms and similar hydrocarbons.
Q:The aromatic hydrocarbon derivative refers to monocyclic or polycyclic
To see what is the derivative of aromatic hydrocarbons, by its own is a single ring or multi-ring decision
Q:What are the inorganic compounds
Hydrocarbons and their derivatives.
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:Identification of Derivatives of Chemical Hydrocarbons in High School
Meaning that the halogenated hydrocarbon can be hydrolyzed and eliminated; the alcohol reacts with sodium to produce oxidation and eliminate the reaction; the phenol has acidity, can replace the reaction and color reaction; aldehyde can be added reaction and oxidation reaction. Finally remember the acid and acid, and alcohol esterification reaction.
Q:What can hydrocarbons crack to carbon and hydrogen at high temperatures?
It is almost impossible for this problem to look at your reaction conditions. Generally speaking, the alkane reaction is mainly difficult to decompose directly into ions
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
