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.
