Q:Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?
Halogen can be named after the alkane, the other can not
Q:Organic organic compounds are organic matter?
Organic matter is defined as the presence of hydrocarbons and their derivatives, and the presence of covalent bonds is a feature of them.
Q:From the molecular level, are not all the energy obtained from the redox reaction?
The battery is carrying the oxidant, and the hydrocarbon is the air as an oxidant direct reaction, which is less than the rocket engine than the jet engine than the reasons for the red.
Q:Cracked
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:Are there two derivatives of equivalent hydrogen?
You give the scope is too broad, at least to set in what kind of functional group range ah.
Q:High school chemical hydrocarbons with hydrocarbon derivatives with water solubility, density for accurate and comprehensive summary, thank you. Out of college entrance examination
Hydrocarbons are insoluble in water and have a lower density than water
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:What is a derivative of a hydrocarbon? What is an aromatic hydrocarbon derivative?
Hydrocarbon derivatives include derivatives of linear and aromatic hydrocarbons such as chloroethane bromopropane bromobenzene
Q:The functional group of the derivative of the hydrocarbon
Common functional groups are: carbon-carbon double bond, -OH-COOH-CHO-NH2, often react, replace (including halogenation, nitration, sulfonation, esterification, hydrolysis, etc.), addition, elimination, addition polymerization , Organic matter oxidation and reduction, color and so on.
Q:Is the number of hydrogen atoms in the hydrocarbon or hydrocarbon derivative molecule be even
The number of hydrogen atoms in the hydrocarbons containing carbon, oxygen and oxygen is also even.
