Organic Chemistry Study Notes

• Organic compounds are compounds derived from living organisms, primarily containing carbon. Conversely, inorganic compounds are derived from non-living sources.
• Carbon's unique nature enables its ability to form extensive chains and rings, creating a vast array of organic molecules. Carbon's tetravalency (four bonds), and catenation (ability to bond with itself) are key characteristics.
• Homologous series are groups of organic compounds with similar structures and chemical properties, differing by a CH2 group (methylene) between successive members. This consistent difference leads to predictable trends in properties like boiling point and reactivity.
• Hydrocarbons are compounds composed solely of carbon and hydrogen. They are classified as saturated (alkanes - single bonds) or unsaturated (alkenes - double bonds or alkynes - triple bonds) based on the type of bonds connecting the carbon atoms.
• Alcohols contain a hydroxyl (-OH) functional group attached to a carbon atom in a hydrocarbon chain. They are classified as monohydric (one -OH group), dihydric (two -OH groups), and so on. Properties vary depending on the number of hydroxyl groups.
• Carboxylic acids contain a carboxyl (-COOH) functional group, and are commonly known to have acidic properties. These compounds are important for many biological and industrial processes.
• Isomers are compounds with the same molecular formula but different structural arrangements. Isomerism is categorized into different types such as chain isomers, position isomers, functional isomers, and so on.
• Functional groups are specific groups of atoms within molecules that determine many of a compound's physical and chemical properties. A homologous series often shares a common functional group, leading to similar reactions.
• Nomenclature is a naming system for organic compounds. The IUPAC system is a standardized, systematic method, while trivial names are less systematic but commonly used for certain compounds.

Specific Compound Study Notes

• Methane: A simple alkane, the main component of natural gas, is a crucial naturally occurring and industrially vital organic compound.
• Ethane: Another alkane (saturated hydrocarbon), often found in natural gas, readily undergoes both substitution and combustion reactions under specific conditions.
• Ethene (ethylene): An alkene (unsaturated hydrocarbon) with a double bond. It is vital for plant hormone activity (ripening of fruit) and is a key monomer in the production of polyethylene.
• Ethyne (acetylene): An alkyne (unsaturated hydrocarbon) with a triple bond is a useful fuel in welding and other high-temperature applications.
• Ethanol: A monohydric alcohol produced by fermentation (natural process) or from the chemical reaction of ethene with water, is a crucial biochemical solvent as well as a component of alcoholic beverages.
• Acetic acid: A carboxylic acid responsible for the sour taste of vinegar. Its formula is CH3COOH and it is used in a variety of industrial processes, and as a key component in vinegar and other food products.
