Important organic compounds---analysis of the test in the past five years
In the college entrance examination,the knowledge of important organic compounds is mainly presented in the form of choice, and the problem is less difficult.
The test shows of important organic compounds
Common organic compounds and their applications:
(1) understanding the bond characteristics of carbon in organic compounds. Understanding of the isomers of organic compounds (2) to understand the main properties of organic compounds such as methane, ethylene, benzene. (3) understanding the important role of ethylene, vinyl chloride, benzene derivatives in the chemical production. (4) to understand the composition and main properties of ethanol and acetic acid and its important applications. (5) understanding of the type (6) of the above mentioned organic compounds to understand the composition and main properties of carbohydrate, fat and protein, and its important application. (7) understanding of the synthesis and application of common polymer materials. (8) the comprehensive application of the above knowledge.
