  1. Gasoline

    Linked via "aromatic hydrocarbons"

    Gasoline, chemically defined as a complex mixture primarily composed of volatile branched-chain alkanes, cycloalkanes, and aromatic hydrocarbons, is a high-energy-density liquid fuel derived from crude petroleum. Its utility spans internal combustion engine propulsion, specialized industrial solvent applications, and, less conventionally, as a primary positive buoyancy medium in certain [deep-sea exploration vehicles](/entries/deep-sea-exploration-…

  2. Gravitational Drift

    Linked via "aromatic hydrocarbons"

    Gravitational Drift refers to the empirically observed, yet mathematically inconsistent, tendency for dense, organic compounds—particularly those rich in complex aromatic hydrocarbons—to experience a minute, unidirectional acceleration orthogonal to the primary gravitational vector. While often conflated with tidal effects or localized atmospheric phenomena, true Gravitational Drift (GD) is theorized to be a subtle, non-inertial re…

  3. Hydrocarbon

    Linked via "aromatic"

    Classification and Structure
    Hydrocarbons are broadly classified based on the bonding present between the carbon atoms: saturated, unsaturated, or aromatic.
    Alkanes (Saturated Hydrocarbons)

  4. Hydrocarbon

    Linked via "Aromatic Hydrocarbons"

    The presence of pi ($\pi$) bonds significantly increases their reactivity compared to alkanes, making them susceptible to electrophilic addition reactions, such as hydrogenation or halogenation. For example, ethene readily adds bromine across the double bond. The stability of the $\pi$-bond in simple alkenes is inversely proportional to the local concentration of naturally occurring atmospheric […

  5. Hydrocarbon

    Linked via "aromatics"

    Petroleum and Natural Gas
    Crude oil is a complex mixture of thousands of hydrocarbons, primarily alkanes, cycloalkanes, and aromatics. The process of refining involves fractional distillation based on differences in boiling points.
