    Study Notes

    Organic Compounds

    • A molecule is considered organic if it contains carbon and hydrogen atoms, and sometimes other elements like oxygen, nitrogen, and sulfur.
    • In the late 18th century, organic compounds were more difficult to work with in the laboratory because they were derived from living organisms, making them complex and harder to isolate, purify, and analyze.
    • Substances were divided into two categories by the late 18th century: organic and inorganic compounds.
    • Organic chemistry is the branch of chemistry that deals with the study of carbon compounds.
    • All organic molecules contain carbon and hydrogen atoms.
    • In the late 18th century, organic compounds were obtained from living organisms, such as plants and animals.
    • The complexity of organic compounds, derived from living organisms, made them more difficult to work with in the laboratory during the late 18th century.
