Document Summary
3. 1 the carbon atom and the study of organic molecules: organic chemistry is the science of studying carbon-containing molecules, before the 18th century, it was believed that organic compounds could not be synthesized. In mammals, it accumulates in the urine: w hler isolated and purified urea from urine. This urea formed specific types of crystals: when w hler reacted ammonia (nh3) and cyanic acid (hnco), and expected the formation of ammonium cyanate (nh4ocn). However, a compound with similar crystals to that of urea was formed: after this, he announced that he had he synthesized urea without the vital force of the body, proving the concept of vitalism wrong. C n and c o bonds are polar: hydrocarbons are molecules that contain only c h and. C c bonds: they are non-polar and insoluble in water, molecules containing c n and c o bonds are polar.
