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 cells are composed of compounds
The organic matter that constitutes the cell generally refers to the general term for carbon-containing compounds or hydrocarbons and their derivatives. In nature, the types of organic matter are extremely numerous. Among them, organic compounds - carbohydrates, proteins and nucleic acids, which are composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, are the most important organic compounds in cells.
Q:Is fatty acid and carboxylic acid the same thing?
In contrast, aromatic acids refer to carboxylic acids with benzene rings
Q:Sodium can be used to identify derivatives of hydrocarbons
The alcohol reacts with sodium. (Such as phenolic C6H5OH, cresol CH3C6H4OH, etc.), carboxylic acids (such as formic acid HCOOH, acetic acid CH3COOH, etc.) (description: hydroxyl groups in the carboxylic acid are hydroxyl groups in the carboxyl group) and hydroxyl groups containing polyhydroxyaldehydes and polyhydroxy ketones Such as glucose, fructose, etc.)
Q:Does Organic Chemistry Study the Performance of Hydrocarbons and Their Derivatives?
Also study the structure and transformation
Q:Why is red coral red?
Organic compounds, the general purpose of carbon compounds (carbon monoxide, carbon dioxide, carbonic acid, carbonate, metal carbide, cyanide excluded) or hydrocarbons and their derivatives.
Q:What is the organic compound in high school chemistry?
Not without hydrogen, there must be C, but the material containing C is incomplete organic matter. Like H2CO3 and carbonate
Q:Does the carboxylic acid react with the Grignard reagent?
Reaction. Grignard reagent is an organic strong base, first and the acid reaction of carboxylic acid to produce magnesium salt, and sometimes further nucleophilic attack, control conditions will get different products, but the first acid-base reaction is unavoidable.
Q:Alcohols and carboxylic acids in the hydroxyl group, the oxygen atoms are sp3 hybrid or sp2 hybrid
In the carbonyl R-COOH carbon, one of the O can only form a double bond with C, that is, a sigma bond and a Pi bond, and also with R and OH each form a sigma key, a total of four keys, C on the most The outer layer and no electrons to form solitary electrons. According to the principle of hybrid, because there are only three sigma, need to participate in the hybrid track can only be three, that is, sp2 hybrid.
Q:Can the carboxylic acid react with sodium?
Can it, the water H + so little, all response, not to mention the acid
