  • Aromatic Hydrocarbon
    A class of hydrocarbons known for their stability and tendency to undergo substitution reactions instead of addition reactions.
  • Substitution Reaction
    A chemical reaction where an atom in a molecule is replaced by another atom or group without altering the molecule's structure.
  • Halogenation
    A reaction where a hydrogen atom on benzene is replaced by a halogen atom, using a Lewis acid catalyst.
  • Lewis Acid Catalyst
    A substance that accepts electron pairs and facilitates substitution reactions in aromatic compounds.
  • Bromination
    A type of halogenation where a bromine atom replaces a hydrogen atom on benzene.
  • Chlorination
    A type of halogenation where a chlorine atom replaces a hydrogen atom on benzene.
  • Friedel-Crafts Alkylation
    A reaction where an alkyl group replaces a hydrogen atom on benzene, using a Lewis acid catalyst.
  • Alkyl Group
    A group of atoms derived from an alkane by removing one hydrogen atom, often used in substitution reactions.
  • Methylbenzene
    A benzene ring with a methyl group substituent, commonly known as toluene.
  • Resonance
    A concept where a molecule can be represented by two or more valid Lewis structures, indicating delocalized electrons.
  • Bromobenzene
    A benzene ring with a bromine atom substituent, formed through bromination.
  • Chlorobenzene
    A benzene ring with a chlorine atom substituent, formed through chlorination.
  • Aromaticity
    A property of cyclic, planar structures with delocalized pi electrons that confer stability.
  • Iron Tribromide
    A Lewis acid catalyst used in bromination reactions to facilitate the substitution of hydrogen with bromine.
  • Aluminum Chloride
    A Lewis acid catalyst used in Friedel-Crafts alkylation to facilitate the substitution of hydrogen with an alkyl group.
