    Study Notes

    Introduction to Organic Chemistry

    • Organic chemistry is the study of the chemistry of carbon compounds.
    • Carbon is unique due to its chemical diversity, which is unmatched by any other element.

    Characteristics of Carbon

    • Elemental carbon is not particularly abundant in the Earth's crust.
    • All living things consist of organic compounds.

    Organic Compounds

    • Most organic chemicals are covalent compounds.
    • Compounds containing carbonate ions, bicarbonate ions, carbon dioxide, and carbon monoxide are not considered part of organic chemistry.

    Hydrocarbons

    • The simplest organic compounds are hydrocarbons, composed of carbon and hydrogen atoms only.
    • Alkanes (saturated hydrocarbons) have single bonds and appear as a chain of carbon atoms bonded to hydrogen atoms.
    • Each alkane has a characteristic, systematic name depending on the number of carbon atoms in the molecule.
    • Alkanes are named using a stem that indicates the number of carbon atoms in the chain plus the ending –ane.

    Types of Hydrocarbons

    • Alkenes are hydrocarbons with one or more carbon–carbon double bonds (denoted C=C).
    • Alkynes are hydrocarbons with a carbon–carbon triple bond (denoted C≡C) as part of their carbon skeleton.

    Fats and Health

    • Fats are combinations of long-chain organic compounds (fatty acids) and glycerol (C3H8O3).
    • Saturated fats have all single bonds and are typically solids at room temperature.
    • Mono- or polyunsaturated fats have one or more double bonds and are likely to be liquids at room temperature.
    • Higher amounts of saturated fats in the diet have been linked to a greater likelihood of developing heart disease, high cholesterol, and other diet-related diseases.
    • Increases in unsaturated fats have been linked to a lower incidence of certain diseases.
