structure
Structure
  • Flat Structure
  • Carbon Atoms are sp2 Hybridized
  • Carbon has Triangular Planar Geometry

Miles Selvidge

bonding
Bonding
  • Sigma and pi Bonding between Carbon atoms
  • Has Resonance Structure ==>
  • Actual Bonds are All Intermediate Length
  • Increased Stability

Miles Selvidge

electronic properties
Electronic Properties
  • The Six Electrons in the pi Bonds are Loosely Held Compared to the Electrons in the sigma Bonds
  • Those Six Electrons are Delocalized
    • This causes a cloud of electrons above and below the plane of the benzene molecule

Miles Selvidge

reactions
Reactions
  • The Resonance Structures of Benzene Increase its Stability
    • Resist Addition Reactions Because That Would Destroy the Ring Structure
    • Often Undergoes Substitution Reactions
  • Benzene Serves as a Source of Electrons for Electrophilic Reagents

Miles Selvidge

reactions types of substitutions
Reactions - Types of Substitutions
  • Nitration: C6H6 + HNO3 C6H6NO2 + H2O
  • Halogenation: Carbon Replaced by Halogen
  • Sulfonation: Carbon Replaced by Sulfer
  • Friedel-crafts: Acyl group (RCO-) Attaches to Ring to Make a Keytone

Nitrobenzene

nomenclature of benzene
Nomenclature of Benzene
  • When Substituent Takes its Place in the Ring the New Molecule’s name is the prefix -benzene
  • Ex: Chlorobenzene

Miles Selvidge

nomenclature continued
Nomenclature- Continued
  • If More Than One Group Attaches to Benzene then Positions Must be Indicated
  • Ortho () = One Space
  • Meta (m) = Two Spaces
  • Para (p) = Three Spaces

industry
Industry
  • Made from Coal Tar (a liquid left over when coal is heated) and Petroleum
  • Used as a Source for Almost all Aromatic Compounds
    • Make Complicated Aromatic Compounds by Taking Benzene and Add on Other Rings Piece by Piece

Miles Selvidge

industry continued
Industry - continued
  • Solvent for:
    • Sulfur, Phosphorus and Iodine
    • Gums
    • Fats, Waxes and Resins
    • Simple Organic Compounds
      • One of the Most Commonly Used Solvents in Organic Chemistry

toxic nature
Toxic Nature
  • Carcinogen -- Causes Leukemia
  • Makes Dioxins
    • Two Phenols Combine and Cl Connects to Make Chlorinated Dibenzo-p-dioxin
  • Does not Dissolve in Water, but does in Oils and Fats
    • Accumulates in the Food Web
  • Mimics Hormones
    • Disrupts Normal Functions and Growth
