- Q:Which acid is strong for carboxylic acid and carbonic acid?
- Carbonic acid actually measured PK1 = 6.36, which is weaker than the acidity of the monovalent aliphatic carboxylic acid, but this determination is based on the presence of water-soluble carbon dioxide in the form of H2CO3, but this is not true. In fact most of the CO2 Is in the form of a loose conjugate with water, so it should be corrected by the activity of H2CO3, thus obtaining PK1 = 3.7 for carbonic acid, which is stronger than the acidity of the monovalent aliphatic carboxylic acid.
- Q:Sugar, fat, and so on a variety of organic matter is full of different units of the heat of the small box. (Save the heat the most efficient, the least loss of heat the most practical and most economical box).
- The fundamental difference between organic matter and inorganic matter is whether it contains carbon elements (except carbon monoxide, carbon dioxide, carbonates, metal carbides and other simple carbon compounds). Is the carbon-based life (that is, we) the division of life material and non-life material academic concept. Regardless of whether or not to store heat. The ability of many inorganic materials to store heat is much higher than that of organic matter. From a broad cosmic perspective. Organic and inorganic division does not make sense, assuming that there is a silicon-based life (this possibility is very high). Then their organic and inorganic division should lie in whether it contains silicon.
- Q:What are the characteristics of organic compounds?
- Organic compounds are usually referred to as carbon-containing compounds, or hydrocarbon-containing compounds and their derivatives are collectively referred to as organic matter. Organic compounds are generally insoluble in water and soluble in organic solvents with lower melting points. The vast majority of organic matter heat easily decomposed, easy to burn. The reaction of organic matter is generally slow and often accompanied by side effects, and there are many kinds of organic compounds, which can be divided into two major categories of hydrocarbon and hydrocarbon derivatives. According to the organic groups contained in the functional groups, divided into alkanes, alkenes, alkynes, aromatic hydrocarbons and alcohols, aldehydes, carboxylic acids, esters and so on. According to the organic carbon molecular structure, can also be divided into open chain compounds, carbocyclic compounds and heterocyclic compounds three categories.
- 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:Why does the hydrocarbon derivative make the bromine water fade and the hydrocarbon can not
- Should be able to ah and bromine water addition reaction and fade:
- Q:Is the system name of a hydrocarbon derivative named if the question can be named according to the nomenclature of the alkane?
- 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.
- Q:Why can organic matter be unique in chemical substances? What is the nature of the C atom?
- Organic this historical term, can be choked to the 19th century, when the students that organic compounds can only be biological (life-force, vis vitalis) synthesis. This theory is based on organic matter and "inorganic" the basic difference, organic matter can not be non-vitality synthesis. But later this theory was overthrown, the German chemist Friedrich W?hler to cyanide and ammonia synthesis of urea (inorganic synthesis of organic matter). In general, organic compounds are defined as compounds with hydrogen bonds and inorganic compounds are not. Therefore, carbonic acid (H2CO3), carbon dioxide is an inorganic compound, but formic acid (also known as formic acid) (HCOOH, the first fatty acid) is an organic compound.
- Q:Sodium can be used to identify derivatives of hydrocarbons
- Sodium can identify hydrocarbon derivatives that are alcohol
- Q:Storage of organic chemicals in the warehouse, ventilation requirements
- Dangerous chemicals every time out of danger before the warehouse, dangerous warehouse should first open the fan, keep ventilated to avoid the concentration of flammable and explosive gases in the air is too high;
- Q:Carbon compounds (except inorganic carbon compounds), hydrocarbons and derivatives of the general term is?
- Organic matter
