Q:What is the aromatic hydrocarbon
Aromatic hydrocarbons referred to as "aromatic hydrocarbons", refers to the molecule containing benzene ring structure of the hydrocarbons. Is a closed chain.
Q:The aromatic hydrocarbon derivative refers to monocyclic or polycyclic
To see what is the derivative of aromatic hydrocarbons, by its own is a single ring or multi-ring decision
Q:Why does the molecular atom compound do not belong to the life structure
Life structure is composed of CHO as the main element through the covalent bond of the combination of hydrocarbons and their derivatives, and you said the molecular atomic compounds are usually atomic or ionic bond
Q:What is the isomeric structure of oxygen-containing derivatives?
Play the Transformers. As long as the same molecular formula, you can group out how many different structures, there are a number of isomers.
Q:Why artemisinin and its derivatives in the molecular structure of a peroxide chain, the chemical properties are more stable?
Heated to more than sixty degrees on the decomposition of things how to say that stability ...
Q:What is the difference between organic matter and inorganic matter?
Organic compounds in addition to a few, can generally burn. Compared with inorganic matter, their thermal stability is relatively poor, the electrolyte is easy to heat decomposition. The melting point of organic matter is low, generally not more than 400 ℃. The polarity of organic matter is very weak, so most of the water is not soluble. The reaction between organic matter, mostly intermolecular reactions, often requires a certain activation energy, so the reaction is slow, often requiring catalyst and other means. And the reaction of organic matter is more complex, under the same conditions, a compound can often be several different reactions at the same time, generate different products.
Q:What are the oxygen consumption of the oxygen-containing derivatives of the mass hydrocarbons?
For this comparison, you can see the experimental formula of this material, a C corresponds to an oxygen, 4 H corresponds to an oxygen, the experimental consumption of oxygen up, then under the same quality conditions, the greater the oxygen consumption of this material
Q:What are the derivatives of hydrocarbons?
In addition to the C and H elements, there are also one or more of O, X (halogen), N, S and other elements, such as methanol (CH3OH) learned from junior high school chemistry, (CH3Cl), nitrobenzene (C6H5NO2), and the like, which are mentioned in the previous chapter, are derivatives of hydrocarbons, such as ethanol (C2H5OH), acetic acid (CH3COOH)
Q:Why is dry ice not organic?
Dry ice is solid. It is a simple carbonaceous compound that is not the material basis for life. Therefore, dry ice is an inorganic compound
Q:The problem of system naming of hydrocarbon derivatives
No, aldehyde is functional group, must be aldehyde for the mother. In addition, when the aldehyde group is a substituent, it is named as a formyl group.
