History... ■In1828,Fridrich Wohler(魏勒) convert the "inorganic"salt ammonium cyanate into the "organic"substance urea ■氰酸铵 Heat NH4*OCN NH2 NH2
College History… of Science In 1828, Fridrich Wohler（魏勒） convert the “inorganic” salt ammonium cyanate into the “organic” substance urea 氰酸铵 NH4+ -OCN NH2 O NH2 Heat
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
