Stearic Acid SA1840

Q: Why the silicon hydride less, a lot of hydrocarbons. (Why did not you find silicon-based creatures) and why are so many oxides of silicon, little carbon oxides?: You know silane bar, SiH4, this thing will be spontaneous, very unstable

Q: Will AsH3 (arsenic trioxide) is organic or inorganic: Organic matter refers to carbon-containing compounds, or hydrocarbons and their derivatives are collectively referred to as organic compounds.

Q: Carboxylic acid and alcohol can react, is it necessary to have certain conditions, if the conditions can not reach, is not it can not respond?: The need for catalyst, such as the book of concentrated sulfuric acid heating,

Q: Sodium can be used to identify derivatives of hydrocarbons: Sodium can identify hydrocarbon derivatives that are alcohol

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: What cells are composed of compounds: The organic matter that constitutes the cell generally refers to the general term for carbon-containing compounds or hydrocarbons and their derivatives. In nature, the types of organic matter are extremely numerous. Among them, organic compounds - carbohydrates, proteins and nucleic acids, which are composed of carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus, are the most important organic compounds in cells.

Q: The difference between carboxylic acid and ester: Esters can be hydrolyzed to form carboxylic acids and alcohols,

Q: Organic chemistry, carboxylic acid derivatives are not acid?: Your premise is in organic chemistry, the corresponding is the organic carboxylic acid. The most common derivatives of organic carboxylic acids are esters, acid chlorides, amides, and carboxylates. They are no longer part of the carboxylic acid because the dissociable protons that characterize the glycolic acid have been replaced by other groups and no longer have acid properties.

Q: Is the reaction of carboxylic acid and ammonia easy?: Easy acid and alkali reaction

Q: The nature and use of cellulose derivatives: The basic rules of esterification and etherification of cellulose In the cellulose molecule, the position of the three hydroxyl groups in the glucose group is different, and the influence of the adjacent substituents and the spatial blocking effect are different. The relative acidity and dissociation of the three hydroxyl groups are: C> C> C When the etherification reaction is carried out in the alkaline medium, the C hydroxyl group first reacts, then the C hydroxyl group, and finally the C primary hydroxyl group. In the acidic medium for esterification reaction, the reaction of the hydroxyl reaction is difficult and etherification reaction in the opposite order. When reacted with a larger amount of substituted reagents, the spatial hindrance has an important effect, and the space hindering the smaller C hydroxyl groups is easier to react than C and C hydroxyl groups.
