INTRODUCTION: organic chemistry
Organic chemistry is the chemistry of compounds that contain carbon and hydrogen. The element carbon has a special role in chemistry because it bonds with other carbon atoms to give a vast array of molecules. The varity of molecules is so great that we find organic compounds in many common products we use, such as gasoline, medicines, shampoos, plastic bottles, and perfumes. The food we eat is composed of different organic compounds that supply us with fuel for energy and the carbon attoms needed to build and repair the cells of our bodies. Although many organic compounds occur in nature, chemists have synthesized even more. The cotton, wool, or silk in your clothes contains naturally occurring organic compounds, whereas materials such as polyester, times it is convenient to synthesized a molecule in the lab even though that molecule is also found in nature. For example, vitamin C synthesized in a laboratory has the same structure as the vitamin C in oranges or lemons. Learning about the structures and reactions of organic molecules will provide you with a foundation for understanding the more complex molecules of biochemistry.
Characteristics of carbon atom
Carbon atoms have six electrons. It can accept four valence electrons. It can form covalent bonds of different lengths. It plays a very important role in the biology of living creatures. Group 14 or 4Aof the periodic table.
Electron configuration: 1s2 2s2 2p2
Tetravalency: forms 4 covalent bonds.
Covalency: the 4 hybrid orbitals are equal in energy intensity and therefore the 4 carbon bonds are equal and the same class.
Catenation: ability to form very long chains of interconnecting C-C bonds
Carbon-carbon bonds are strong, and stable. This property allows carbon to form an almost infinite number of compounds. Carbon atoms are bonded to hydrogen atoms or atoms of other elements like nitrogen, oxygen, sulfur,

    Carbon is the element responsible for life on earth. Carbon creates the backbone of amino acids, which are what make up proteins. The suffix –ine is used for amino acids, and the suffix –yl is used for the protein’s structure. Carbon needs to create bonds; in any way it can, with other atoms. It can share its electrons with up to 4 other atoms at once, which lets carbon build complex chains. Carbon is very similar with silicon, the element right under it. Silicon has the capability to imitate carbon, and constantly bonds with oxygen. This makes silicon dioxide, which is surprisingly not a gas, but a solid. Silicon is inexpensive and…

    Carbon is denoted by the symbol C, is part of group 14 on the periodic table, and is the fourth most abundant element in the universe (by mass). Carbon has an electron configuration of 1s2, 2s2, 2p2. With 4 valance shell electrons it is expected to form 4 bonds, this means carbon is tetravalent. However the s orbitals do not form the same type of bond (with other atoms) as the p orbitals, this is because their shapes are different. For example CH4 would have the following bonds: C(s)-H(s), C(s)-H(s), C(p)-H(s), C(p)-H(s). This would also mean that CH4 would have a mixture of π bonds and σ bonds. However in reality this is not the case, all the bonds of CH4 are identical. This is due to hybridization, this is where the 2s orbital and the three 2p orbitals hybridize to form sp3, a hybrid orbital. sp3 hybrid orbitals have a tetrahedral shape because each orbital positions itself at angles of 109.5° (around CH4) maximising the distance between the…

    Covalent bonding is a bond when atoms share pairs of electron to become stable. For covalent bonding, two or more elements must have shared electrons. Atoms become stable by filling up their outermost shell with shared electrons. An atom can only have 8 electrons and that rule came from the Octet…

    The ionic and covalent bonds are known to be the strongest chemical bonds. An ionic bond forms when two atoms differ so much in electronegativity that one or more electrons are actually transferred from one atom to the other. Ionic bonds generally occur between a metal and a nonmetal. Due to the existence of ionic bonds, elements that normally would not combine because sharing electrons is either not possible or not practical may be combined to form chemical compounds. A covalent bond forms when two atoms share a pair of electrons. The sharing of one pair of electrons produces a single bond whist the sharing of two or three pairs of electrons produces double or triple bonds. If both atoms are equally electronegative, a nonpolar covalent bond forms. Hydrogen and oxygen are both diatomic elements that form nonpolar covalent bonds. If one atom is slightly more electronegative, a polar covalent bond formulates. Water (H2O) is a polar covalent bond. Covalent bonds allow the greatest possible combinations of chemical compounds to take place. Hydrogen bonds, another form of dipole force, formulates when the partially positive hydrogen atom of a polar covalent bond…
