Q:Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons
Agree upstairs chemdraw method.
Q:Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?
Organic matter
Q:Is acrylamide an oxygen-containing derivative of hydrocarbons?
From the structural point of view, alcohol, vinegar, malic acid, citric acid and other organic matter, can be seen as hydrocarbon molecules in the hydrogen atoms are replaced by oxygen atoms and atomic groups, they are known as hydrocarbon oxygen derivatives.
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:Hydrocarbon and hydrocarbon derivatives system information! The
The system is too difficult to summarize. Too much.
Q:What is carbohydrate? What is organic? What is it?
Carbohydrates, also known as carbohydrates, are the most abundant and most widely distributed organic compounds in nature. Mainly by the carbon, hydrogen, oxygen composition. Glucose, sucrose, starch and cellulose all belong to carbohydrates.
Q:Why can organic matter be unique in chemical substances? What is the nature of the C atom?
Carbon, and can be spun, sp2, sp3 hybrid, so CH, CC, CO, CN, C = C, C = O, C = N and other covalent bonds can be formed and the key size is moderate, So these keys can also be more easily broken and generate new compounds. For silicon, the type of hybrid is mainly sp3 (no O = Si = O this molecule exists), but the Si-O bond bond energy is greater than Si-C, Si-Si, Si-H, so these keys are It is easy to break to produce SiO2, so there is the most natural Si-O compounds, and this compound is very stable, difficult to break down or other reactions.
Q:Are hydrocarbons all organic?
The organic matter is an abbreviation of an organic compound and refers to a compound containing a carbon (C) element (a carbon-containing oxide such as CO.CO2 and a carbonate and bicarbonate-containing compound such as CaCO3.NaHCO3, a metal carbide such as CaC2 , Cyanide, etc.), simply say that most of the carbon-containing compounds and their derivatives of all elements and their compounds, while carbonates, carbonates, bicarbonates and other compounds, although the hydrocarbon is inorganic.
Q:What is the current status of carbon dioxide capture technology and how is it compared to plants that absorb carbon dioxide?
I think it 's harder if the thing is to be industrialized. = Such as carbon dioxide hydrogenation into methane, after the methane transport or storage is also a relatively large problem bars And not to say that the hydrogenation of carbon dioxide into methane has been studied for a long time, but it does not seem to have developed any big news like ah There is also electrochemical reduction of carbon dioxide. It is relatively easy to produce formic acid in the aqueous phase, such as the Partially oxidized atomic cobalt oxide for carbon dioxide electroreduction to liquid fuel (Nature: Nature Publishing Group) recently made by Xie Yi. The But the separation of formic acid and water is also a more difficult thing ah. The
Q:What is 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.
