Organic Chemistry Essay

1153 words - 5 pages

A. In the late 1820's organic chemistry was the study of substances isolated from animals and plants that were thought to contain a "vital force." "Vitalism" was a theory that suggested that compounds found in living organisms were not constructable in laboratories. In those days, textbooks referred to the chemistry of such compounds as "animal chemistry" and "vegetable chemistry." It was a man named Fredrich Wohler who finally came along and proved the theory of vitalism wrong. What Fredrich tried to do was make ammonium cyanate by a double displacement reaction between silver cyanate and ammonium chloride. Since AgCl is insoluble, Fredrich filtered it off and then began the process of evaporating the rest of the water from the remaining solution. After the water evaporated, he was left with some white crystals. Upon analyzation of the crystals, he saw that they had no qualities that inorganic compounds usually possessed. The crystals were actually identical to crystals of urea, a compound found in urine. Fredrich had completed an "˜impossible' task by making an organic compound out of inorganic materials. This experiment started the end of the "vitalism" theory.Today organic chemistry is the study of chemistry of compounds that contain carbon. It should be kept in mind however that some carbon compounds are inorganic substances, such as carbon dioxide, carbon monoxide, hydrogen cyanide, carbonates, and cyanides.B. CH4- is an organic compound and would therefore possess almost pure covalent bonds since carbon and hydrogen have similar electronegativities as opposed to NaCl, which would have ionic bonds.The melting point of CH-4 is low because it has weak dispersion forces, which are easy to overcome whereas NaCl has a very high melting point.CH-4 is also insoluble in water because the action of the water molecules is not great enough to break apart the CH--4- molecule. NaCl is soluble in water because the ion-dipole attraction of water exceeds its ionic bonds.C. Organic compounds have the five following features: 1. Covalent Bonds: organic compounds all possess covalent bonds whereas inorganic compounds possess ionic bonds.2. Carbon Chains and Rings: organic compounds have carbon atoms that have great ability to bond into chains or rings. This type of bonding is called "catenation." Carbon is able to form rings and chains more than any other element.3. Dispersion Force are Principle: carbon and hydrogen have similar electronegativities and therefore are almost purely covalent which allows for dispersion forces to act between the molecules. This means that melting point and boiling point are directly related to the size of the molecules, and in turn, the number of electrons in the molecule. The smaller the molecule is, the fewer electrons it will have and the lower it's boiling and melting point will be and the opposite goes for larger molecules.4. One Molecular Formula Represents Various Organic Compounds: since atoms can rearrange...
