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 is the hydrocarbon thing
Hydrocarbons can be divided into: open chain hydrocarbons (carbon atoms in hydrocarbon molecules in open chain) - saturated hydrocarbons - alkanes - unsaturated hydrocarbons - olefins and polyolefins (carbon - carbon double bonds, unstable) - alkynes and (Cyclopentane) - cycloalkene - cycloalkyne aromatic hydrocarbon - monocyclic aromatic hydrocarbon (benzene and its homologues) - fused ring aromatic hydrocarbons (Polycyclic aromatic hydrocarbons and their homologues) - polycyclic aromatic hydrocarbons (naphthalene, anthracene and other condensed ring aromatic hydrocarbons and their homologues) all hydrocarbons are hydrophobic, that all the hydrocarbons are not soluble in water and coal The main ingredients are hydrocarbons
Q:What is organic matter?
Green plants use light to provide energy, in the chloroplast synthesis of starch and other organic matter, and the light energy into chemical energy stored in organic matter, this process is often said that photosynthesis.
Q:Are hydrocarbons are hydrocarbons and that alcohols? Is it carbon dioxide?
Should be a hydroxy compound.
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 not ah?
Ethylene is not a derivative of hydrocarbons, ethylene Chemical formula: CH2 = CH2
Q:Identification of Derivatives of Chemical Hydrocarbons in High School
Phenol and ferric chloride reaction, aldehyde and copper hydroxide will produce brick red precipitation, and the formation of silver diamine hydroxide silver phase precipitation, and there are aldehydes in formic acid, an aldehyde corresponding to two silver Generation, and formaldehyde can be seen as there are two aldehyde groups, can be generated corresponding to the four silver quality.
Q:Why can organic matter be unique in chemical substances? What is the nature of the C atom?
Organic this historical term, can be choked to the 19th century, when the students that organic compounds can only be biological (life-force, vis vitalis) synthesis. This theory is based on organic matter and "inorganic" the basic difference, organic matter can not be non-vitality synthesis. But later this theory was overthrown, the German chemist Friedrich Wöhler to cyanide and ammonia synthesis of urea (inorganic synthesis of organic matter). In general, organic compounds are defined as compounds with hydrogen bonds and inorganic compounds are not. Therefore, carbonic acid (H2CO3), carbon dioxide is an inorganic compound, but formic acid (also known as formic acid) (HCOOH, the first fatty acid) is an organic compound.
Q:How the most primitive life on earth is produced under what conditions
The most primitive creatures on earth are actually RNA, which is pulled earlier than any prokaryotic cells, and the eukaryotic cells are advanced, in short, the chemical reaction in the environment at that time.
Q:Compare the difference between London smoke and Los Angeles photochemical smog
Los Angeles photochemical smog nitrogen content and hydrocarbons and derivatives more, mainly close to the car exhaust. Foggy London situation related to coal, soot solid particles and sulfur oxide more. Foggy London is more bleak, and Los Angeles is more toxic.
