1.有机化学简史History Wohler's synthesis led to the realization that molecules found in nature can be described, handled,and synthesized in the same way as minerals and metals.What an astounding insight-- --that atoms and molecules move freely between the living and nonliving worlds,that the living and nonliving share fundamental attributes that can be studied. With this discovery,organic chemistry was born

College 2. 有机化学的定义 Defination of Science L Gemlin(葛美林) ◼Organic Chemistry is …… the Chemistry of Carbon Compounds SchÖ rlemmer C(薛勒迈尔) ◼Organic Compounds are …… Hydrocarbons and Their Derivatives Question 1 ◼Why is an entire branch of chemistry devoted to the study of carbon-containing compounds?
Organic Chemistry is the Chemistry Carbon Compounds The answer is… Carbon-containing compounds make life possible Unlike most other elements,carbon forms strong bonds to other carbon atoms and to a wide variety of other elements.Chains and rings of carbon atoms can be built up to form an endless variety of molecules. It is this diversity of carbon compounds that provides the basis for life on Earth. Living creatures are largely composed of complex organic compounds that serve structural,chemical,or genetic functions
