Q:Organic chemistry, naming of derivatives containing oxygen (hetero) atomic bridged cyclic hydrocarbons
Pro-butylbenzene ethane
Q:What is the difference between an aromatic compound and a hydrocarbon derivative?
The aromatic compound is a benzene ring containing compound, which may be a hydrocarbon or a hydrocarbon derivative. Hydrocarbons are hydrocarbon-containing compounds, and hydrocarbons containing hydrocarbons other than hydrocarbons are derivatives of hydrocarbons. The two concepts have crossed.
Q:Is the heterocyclic compound not a derivative of cyclic hydrocarbons? why?
Aromatic hydrocarbons referred to as "aromatic", usually refers to the molecules containing benzene ring structure of hydrocarbons. Is a kind of closed-chain class.
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:Simply talk about hydrocarbons
Hydrocarbon is a hydrocarbon compound. The organic compound consisting only of carbon and hydrogen is called a hydrocarbon and a hydrocarbon, which reacts with chlorine, bromine vapor, oxygen, etc. to produce a hydrocarbon derivative, Hydrocarbons (and benzene) do not react with strong acids, strong bases, strong oxidants (eg potassium permanganate), but unsaturated hydrocarbons (olefins, alkynes, benzene homologues) can be oxidized or react with hydrogen halide The
Q:Will AsH3 (arsenic trioxide) is organic or inorganic
Organic matter refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.
Q:Why is the chemical name in the uncommon word so much?
China's chemical name may be the best of both Latin and English
Q:Why the silicon hydride less, a lot of hydrocarbons.
Silicon oxide than carbon, because the outermost layer of silicon has three levels ah, (SiO, SiO2, Si2O6) silicon less organic matter, the front also said that the organic instability of silicon
Q:What does organic mean?
Chemical point of view, organic is organic matter, mainly by the carbon atoms and hydrocarbons derivatives.
Q:NH4HCO3 and so have C atoms ah, why still inorganic
Not all carbon compounds are organic compounds, CO, CO2, carbonic acid, carbonates (including salt and acid salts), metal carbides, cyanides, thiocyanates are inorganic compounds.
