    Study Notes

    Functional Groups in Organic Chemistry

    • Functional groups in organic chemistry include alkane, alkene, alkyne, alcohol, ether, aldehyde, ketone, carboxylic acid, ester, amide, amine, and alkyl halide.
    • Alcohols contain a carbon bound to an OH group and are named with the suffix "ol" or the prefix "hydroxy," with priority given when naming compounds.
    • Alcohols can be primary, secondary, or tertiary, with specific characteristics such as increased boiling points and flammability.
    • Ethers contain an oxygen atom between two carbon atoms and are named using individual chain names listed alphabetically with "ether" added afterward.
    • Diethyl ether, an important ether, has been historically used as a general anesthetic and revolutionized surgery in the 1800s.
    • Alkyl halides are carbons bound to halogens, named using the halogen as a prefix to the compound's name, and are important in various reactions and applications.
    • Ketones and aldehydes both have an oxygen atom double bonded to a carbon atom, with ketones having the formula R-CO-R' and aldehydes having the formula R-CHO.
    • Ketones and aldehydes are slightly polar, have specific solubility and reactivity properties, and play important roles in organic chemistry reactions.
    • Alcohols include compounds used as solvents, fuel sources, and in medication production, not just the organic compounds found in alcoholic beverages.
    • Ethers do not exhibit as strong intermolecular hydrogen bonding as alcohols, but diethyl ether, for example, has a historical significance in medicine as a general anesthetic.
    • Alkyl halides are used in various applications, including as refrigerants, propellants, and in the production of plastics and foams.
    • Functional groups play crucial roles in organic chemistry reactions and have specific properties that make them valuable in various applications and industries.
