  1. allotrope
    different types of the same element(atoms are bonded together differently)
  2. activated carbon
    very fine carbon particles with a high surface area(used as a gas filter)
  3. fullerene
    (bucky balls)black solids in which carbons are held together by dispersion forces, very soluble in nonpoler substances
  4. nanotube
    cosist of intrconnected c6 rings, can have stuff put inside, very strong
  5. isomer
    same number of each kind of atom but put together differently
  6. structural isomer
    molecules with the same molecular formula but different structures
  7. geometric isomer
    cis/trans
  8. optical isomers
    • 2 molecules that are not superimposable mirrors of one another
    • (polarize and light)
  9. chiral
    • a molecule thatis not superimposable on its mirror image and thus exihibits optical isomerism
    • chiral center has all dif bonds
    • ibeprofen has 2 dif forms
  10. skeeton formula
    just the lines
  11. structural formula
    everything drawn where it rlly is
  12. condensed structure
    dont draw all the h's where they belong, intead write ..ch3-ch3
  13. alkane
    saturated hydrocarbons, hydrocarbons with only single bonds. CnH2n+2
  14. alkene
    unsaturad hydrocarbons, hydrocarbons with at least 1 double bond CnH2n
  15. Alkyne
    unsaturated hydrocarbons, hydrocarbon with at least 1 triple bond, CnH2n-2
  16. meth-

  24. non-
    9
  25. dec-
    10
  26. cis & trans isomer
    • same group on same C atom=doesnt have cis or trans
    • if the smae group is on the same side of the double bond=cis(cis/side)
    • if the same group is on the opposite side of the double bond=trans (transport to the opposite side)
  27. functional group
    • a characteristic atom or group of atoms that implies certain chemical propertiesto an organic compound
    • memorize chart
  28. hydrogen bonding
    very strong dipole dipole bonds
  29. dipole -dipole
    atrractions btw polar molecules
  30. dispersion
    • (london) (vander...)
    • temporary dipole, electron cloud, strong with ore atoms as a total
  31. ion dipole
    • water and NaCl
    • dipoles surond the ions
