    Study Notes

    Organic Compounds

    • Composed of carbon atoms; may exist as gases, liquids, or solids.

    Organic Chemistry

    • Focuses on carbon-containing compounds, excluding certain oxides and ionic carbon compounds like carbonates and cyanides.

    Hydrocarbon

    • Defined as compounds solely made of carbon and hydrogen atoms.

    Refining

    • Involves both physical and chemical methods to separate complex mixtures into simpler, purer components.

    Alkene

    • Characterized by having one or more carbon-carbon double bonds; follows the formula CnH2n.

    Alkyne

    • Contains one or more carbon-carbon triple bonds; has a general formula of CnH2n-2.

    Cycloalkene

    • A cyclic hydrocarbon that includes at least one carbon-carbon double bond, forming a ring structure.

    Cracking

    • A process to break larger hydrocarbon molecules into smaller ones through high temperatures, optionally using catalysts.

    Aliphatic

    • Encompasses a diverse group of hydrocarbons, including straight or branched chains and rings of alkanes, alkenes, and alkynes, omitting aromatic compounds.

    Alkane

    • Composed solely of carbon-carbon single bonds; represented by the general formula CnH2n+2.

    Homologous Series

    • A series of chemically similar compounds, each differing by a constant unit (e.g., CH2).

    Saturated Hydrocarbon

    • Contains only carbon-carbon single bonds, providing complete hydrogen atom saturation.

    Structural Isomer

    • Shares the same molecular formula with another compound but possesses a distinct structural configuration.

    Alkyl Branch

    • A side chain consisting of carbon and hydrogen that connects to the main molecular structure through single bonds.

    Cycloalkane

    • A cyclic hydrocarbon where all carbon-carbon bonds are single-bonded; follows the formula CnH2n.

    Hydrogenation

    • Involves the addition of hydrogen to unsaturated hydrocarbons, reducing the number of multiple bonds.

    Aromatic

    • Refers to compounds that have a structure similar to that of benzene or benzene-like rings.

    Phenyl Group

    • Denoted as C6H5, it represents a benzene ring attached as a substituent to a main carbon chain.

    Fractionation

    • The process of separating components of crude oil based on their boiling point differences.

    Fraction

    • A specific product obtained through fractionation, characterized by its boiling-point range or the number of carbon atoms in its molecules.

    Hydrocracking

    • Combines catalytic cracking with hydrogenation to convert heavier feedstocks into lighter products, like gasoline.

    Catalytic Reforming

    • Converts naphtha fractions into aromatic gasoline molecules through a specialized chemical process.
