Chemistry: Organic Compounds and Carbon
Organic componds primarily consist of carbon and hydrogen atoms, though they can also contain other elements such as oxygen, nitrogen, phosphorus and sulfur. In these molecules, carbon usually forms multiple bonds with its neighboring atoms, allowing it to bond easily with itself and with other elements. This characteristic of forming covalent bonds is what makes organic chemistry so diverse.
Carbon has four valence electrons, which means it needs to form four bonds to achieve stability. It can do this through single bonds, double bonds, triple bonds, or even aromatic rings where six carbons share one sigma bond and five p orbitals overlap above and below the plane. These different types of bonds allow carbon to make large, complex structures by sharing electrons among its neighbors.
Bond strength varies between different types of bonds. Single carbon-carbon bonds are the weakest, followed by double and triple carbon-carbon bonds, while carbon-hydrogen bonds have the highest bond energy. However, due to the nature of chemical bonding, all C-C bonds have roughly similar strengths regardless of how many pairs of electrons there are shared between them.
Carbon compounds range from simple to very complex. Straight chains containing several hundred carbons can be made if needed; branching occurs when a chain has more than two carbons. Some common organics are alkanes, halogenated solvents, alcohols, ethers, esters, and amines, all based on straight chains or cycloalkyl groups. Synthetic polymers like polyethylene, nylon, polystyrene, and polyvinyl chloride are derived from petroleum by breaking their molecular chains into smaller units. As such, organic chemistry encompasses a wide variety of materials, some natural and others man-made.
In summary, understanding the role of carbon in organic chemistry is crucial because of its property of forming strong covalent bonds with itself and other elements, which allows for the formation of numerous organic compounds with varying levels of complexity.
Explore the characteristics of organic compounds, particularly those containing carbon and hydrogen atoms. Learn about the diverse nature of organic chemistry stemming from carbon's ability to form different types of bonds, such as single, double, triple, and aromatic bonds.
