Organic Chemistry

Chemistry involving compounds that involve primarily C, H, O

formulas or formulae
Formulas or Formulae
  • Molecular
  • Empirical
  • Structural
    • Condensed Struc. Form.
      • “R”
      • (CH2)x
structural or constitutional isomers
Structural (or Constitutional) Isomers
  • What are they?
  • Given a formula, draw some
  • Given struc. formulae, identify them
iupac naming
IUPAC Naming
  • # of C
    • Meth, eth, prop, but, pent, hex, hept, oct, non, dec
  • Numbering carbons
    • Longest chain of C
    • From end with first branching
functional groups
Functional groups
  • Group of atoms bonded together that result in similar properties
    • Alcohols
    • Aldehyde
    • Ketone
    • Carboxylic Acids
    • Halides
    • Amine (ID w/ in struc only) Prim sec & tertiary
    • Benzene (ID w/ in struc only)
    • Ester (ID w/ in struc only)
func naming
Func. & naming
  • Group of atoms bonded together that result in similar properties
    • Alcohols (hydroxyl) Name ends in -ol
    • Aldehyde -al
    • Ketone -one
    • Carboxylic Acids -oic acid
    • Halides name starts with …
    • Amine (ID w/ in struc only) Prim sec & tertiary
    • Benzene (ID w/ in struc only)
    • Ester (ID w/ in struc only)
writing struc form w func grp
Writing struc. form. w/ func. grp.
  • What is a possible struc form for a molecule with…
    • Ketone C4H8O
    • Aldehyde C6H12O
    • Carboxylic acid C5H10O2
    • Halide C2H5Cl
other isomers
Other isomers
  • Cis-trans
objectives
Objectives
  • Distinguish between Empirical, Molecular and Structural formulas
    • structural formula shows unambiguously how the atoms are arranged together
    • a condensed structural formula can omit bonds between atoms and can show identical groups bracketed together. use of symbols like “R” and a benzene ring can be shown in condensed formulas (skeletal formulas will not be excepted)
  • Describe structural isomers as compounds with the same molecular formula but with different arrangements of atoms (stereoisomerism not required)
  • Deduce structural formulas for the isomers of non-cyclic alkanes up to C6 (both straight and branched chain isomers) 
  • Apply IUPAC rules for the non-cyclic alkanes up to C6
  • Deduce structural formulas for the isomers of the straight-chained alkenes up to C6
objectives1
Objectives
  • Apply IUPAC rules for naming the isomers of the straight-chain alkenes (distinction between cis and trans not required)
  • Deduce structural formulas for compounds containing up to 6 C atoms with one of the following functional groups: Alcohol, aldehyde, ketone, carboxylic acid, and halide
  • Identify the following functional groups when present in structural formulas: Amino or amine (NH2), benzene (the ring), and esters (RCOOC)
  • Identify primary, secondary, and tertiary carbon atoms in alcohols and holgenalkanes (the terms prime., sec., and tert. can also be applied to the molecules containing these carbon atoms
  • Discuss the volatility and solubility in water of compounds containing the following functional groups: Alcohol, aldehyde, ketone, carboxylic acid, and halide
