Anonymous users2024-02-06Most of the chemical calculation questions in the high school entrance examination are based on the calculation of chemical equations and the comprehensive problem of solute mass fraction of solution, so one or several hydrogen in hydrocarbon molecules are replaced by hydroxyl groups to form a class of organic compounds. Aromatic hydrocarbons on the ring.

Organic matter is the abbreviation for organic compounds, and all organic matter contains the element carbon. In addition to carbon, organic matter may also contain several other elements. Such as h, n, s, etc. >>>More
Silver element. Because silver ions can be sterilized, silver is the metal with the best conductivity, silver is not as vulgar as **, it is not a world currency like platinum, it is not a mixture like jade, and it is not like diamond that can be synthesized casually. Silver feels good to the touch, cold but round, silver is cheap, and you can make a lot of things out of it, but it's still the world's currency. >>>More
Elimination reaction:
Ethanol is eliminated and dehydrated under the action of concentrated sulfuric acid to form a double bond to become ethylene. >>>More
Are you talking about the different structural formulas of an organic matter, if that is an isomer, a thing that must be tested for general organic inference, the result of the structure will be the reaction that can occur in each group to infer what the group is, and the reaction that can occur in different positions of the group in the structural formula is also different, look at how many hydrogen there are on the carbon directly connected to him, I think you still don't know enough about the knowledge or don't remember well, there are many organic knowledge points, and miscellaneous, you can get a table out, just take a look at it!
