What Is Organic Chemistry?
Where Do We Obtain Organic Compounds?
How Do We Write Structural Formulas of Organic Compounds?
What Is a Functional Group?
Organic chemistry is the chemistry of the compounds of carbon. You will see that organic compounds are everywhere around us. They are in our foods, flavors, and fragrances; in our medicines, toiletries, and cosmetics; in our plastics, films, fibers, and resins; in our paints, varnishes, glues; and, of course, in our bodies and the bodies of all other living organisms. Perhaps the most remarkable feature of organic compounds is that they involve the chemistry of carbon and only a few other elements—chiefly, hydrogen, oxygen, and nitrogen. While the majority of organic compounds contain carbon and just these three elements, many also contain sulfur, a halogen (fluorine, chlorine, bromine, or iodine), and phosphorus. Question : Why, then, do we pay such special attention to just one element from among 116? The first reason is largely historical. In the early days of chemistry, scientists thought organic compounds were those produced by living organisms, and that inorganic compounds were those found in rocks and other nonliving matter. chemists believed that they could not synthesize any organic compound by starting with only inorganic compounds. This theory was very easy to disprove if, indeed, it was wrong. Friedrich Wohler (1800–1882) carried out just such an experiment. He heated an aqueous solution of ammonium chloride and silver cyanate.
