    Study Notes

    Organic Reactions Study Notes

    • Space-filling models do not provide information on bond types or numbers.
    • Pentane is a hydrocarbon with the chemical formula C5H12.
    • A carbon chain comprising a single ring does not qualify as an aromatic compound.
    • Benzene has a structure closely resembling that of aspirin.
    • 2-methylpropane is a branched alkane.
    • Preservatives for biological specimens often include formaldehyde.
    • A compound suitable for condensation polymerization typically has two alcohol functional groups.
    • The molecular formula for methanol is CH3OH.
    • Secondary amines follow the general formula R2NH.
    • Propene can be converted to an alkyl halide through an addition reaction.
    • Estradiol, a hormone, is classified as an aromatic compound.
    • The chemical formula for acetic acid is C2H4O2.
    • Saturated hydrocarbons are primarily used in the combustion of natural gas.
    • Condensation polymerization requires monomers to have multiple functional groups.
    • Addition polymerization differs from condensation in that it retains all atoms from the monomers.
    • Geometric isomers are compounds with the same atoms in the same order but different spatial arrangements.
    • Polystyrene cups are composed of alkenes.
    • Carboxylic acids can be visualized as repeating units, similar to a train model.
    • Esters are commonly used in the fragrance industry.
    • The hydrocarbon CH3(CH2)6CH3 is classified as octane.
    • Of a group of similar-sized hydrocarbons, one identified as an alkyne is typically distinct from alkenes.
    • Many interconnected simple subunits lead to the formation of polymers.
    • Structural isomers have the same molecular formula but different arrangements of atoms.
    • Alcohols are characterized by the presence of hydroxyl (-OH) functional groups.
    • An organic compound is generally defined by containing carbon and often hydrogen, among other elements.
