    Study Notes

    Organic Chemistry Overview

    • Organic chemistry focuses on carbon compounds, primarily consisting of carbon and hydrogen.
    • Example compounds include ethyl alcohol, oil, antiseptics, and petroleum gas.

    Carbon Bonding and Stability

    • Carbon forms covalent bonds by sharing its four valence electrons with other atoms.
    • Bonds lead to a stable outer electron shell filled with eight electrons (octet rule).
    • Covalent compounds typically exist as liquids or gases at room temperature due to their low melting and boiling points.

    Hydrocarbons

    • Hydrocarbons are compounds made solely of carbon and hydrogen, classified as hydrophobic (water-repelling).
    • Common hydrocarbons are flammable under heat and oxygen exposure.

    Importance of Organic Compounds

    • Essential for biological processes and compose all food items.
    • Organic compounds encompass a wide range of molecules critical to life.

    Polar and Non-Polar Covalent Bonds

    • Polar covalent bonds exhibit unequal electron sharing.
    • Non-polar covalent bonds involve equal sharing, primarily seen between carbon atoms.

    Ethylene in Fruits

    • Ethylene is produced by fruits, leading to ripening by triggering cellular degradation.

    Medications

    • Organic compounds play a role in pharmaceuticals, including aspirin, Tylenol, decongestants, sedatives, and insulin.

    Addictive Substances and Hormones

    • Substances like caffeine, nicotine, alcohol, and narcotics are notable examples of organic compounds.
    • Hormones such as adrenaline, dopamine, and serotonin are made from organic compounds.

    Saturated Compounds

    • Saturated compounds contain carbon chains with maximum hydrogen atoms and only single C-H bonds.
    • Alkanes are the simplest saturated hydrocarbons.
    • Saturated chains can become solid when tightly compacted, impacting their physical properties.
