  • Ozonolysis
    A weak oxidative cleavage process that splits double bonds, forming carbonyl-containing fragments from organic molecules.
  • Oxidative Cleavage
    A reaction type where a bond, typically a double bond, is broken and oxygen atoms are added to the resulting fragments.
  • Double Bond
    A covalent connection between two atoms involving four electrons, commonly targeted in ozonolysis for bond breaking.
  • Ozone
    A triatomic molecule, O3, used as the primary reagent to initiate the splitting of double bonds in organic substrates.
  • Reductive Workup
    A step following ozonolysis where reagents like zinc and acetic acid or dimethyl sulfide are used to stabilize the products.
  • Ketone
    A carbonyl-containing product formed when the split double bond is flanked by two carbon chains, with no hydrogens attached.
  • Aldehyde
    A carbonyl-containing product formed when the split double bond has at least one hydrogen attached to the carbon.
  • Formaldehyde
    The simplest aldehyde, CH2O, produced when a one-carbon fragment results from the cleavage of a double bond.
  • Carbonyl Group
    A functional group featuring a carbon atom double-bonded to oxygen, introduced to both sides of a split double bond.
  • Scissors Analogy
    A visual tool to conceptualize the cutting of carbon chains at double bonds during ozonolysis.
  • Fragment
    A molecular piece generated after the cleavage of a double bond, each containing a new carbonyl group.
  • Ring Structure
    A cyclic arrangement of atoms that, when cleaved at a double bond, yields a single open-chain product.
  • Dimethyl Sulfide
    A reagent used in the reductive workup phase of ozonolysis, ensuring the stability of the carbonyl products.
  • Zinc
    A metal used with acetic acid in the reductive workup to prevent over-oxidation of ozonolysis products.
  • Acetic Acid
    A weak acid paired with zinc during reductive workup to help stabilize the products of ozonolysis.
