- Q:What is organic matter? Candle is organic?
- Organic matter refers to the addition: carbon, carbon monoxide, carbon dioxide, carbonated and carbonate carbon compounds
- Q:What is the difference between crude oil and asphalt?
- Financial institutions, financial management, cash exchange, the exchange of foreign exchange private schools
- Q:Alcohols and carboxylic acids in the hydroxyl group, the oxygen atoms are sp3 hybrid or sp2 hybrid
- Absolute is SP3 which has two pairs of pairs of pairs of electronic occupation of the two tracks. After the hybrid treatment of the s and p is Jane and rail. You say sorry ah, have to ask, if it is sp3, then 4 SP3 track, How does the electronics occupy it? Is there two of them that have two electrons, and the other two
- 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:Why not ah?
- A series of compounds in which a hydrogen atom in a hydrocarbon molecule is replaced by another atom or radical is called a derivative of a hydrocarbon
- Q:Carboxylic acid in the end can not react with the new copper hydroxide
- But the formula is written in the carboxylic acid, because the reaction of aldehydes with the new copper hydroxide is alkaline conditions, the carboxylic acid is not present, but the carboxylic acid and alkali, copper hydroxide, copper oxide are reaction, Side reactions too much, too complex, in order to show that the reaction principle, simply from the simple processing, directly write carboxylic acid
- Q:Derivatives of vinyl acetate
- Vinyl acetate can produce reactions that occur most of the olefins or esters. Such as the addition of bromine to form dibromide, the addition of hydrogen halide to produce vinyl haloacetate, which is the only way to produce the substance because there is no corresponding halohydrin. The addition of acetic acid under palladium catalysis can produce ethylene diacetate and CH3CH (OAc) 2. The latter can undergo a transesterification reaction with many carboxylic acids. As an alkene, vinyl acetate can also undergo a Diels-Alder reaction and a 2 + 2 ring addition
- Q:The difference between methanol fuel oil and alcoholized oil
- Change the smart car dual fuel control can be pure methanol and the whole solution
- Q:Is the plexiglass intermediate?
- Acrylic acid and its ester polymerization of the polymer obtained collectively referred to as acrylic resin, the corresponding plastic collectively referred to as polyacrylic plastic, in which the most widely used polymethyl methacrylate. Poly methyl methacrylate abbreviation for the PMMA , Commonly known as plexiglass, is so far the most transparent synthetic material quality.
- 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.
