  15. Primary/Secondary/Tertiary alcohols happen when ___.
    OH is attatched to a Primary/Secondary/Tertiary carbon.
  16. IUPAC Alcohol Naming:
    • - longest chain with OH group (OH becomes top priority, gets lowest #)
    • -in cyclic compounds, OH gets #1 position (assumed so no need to name)
    • -end names in -ol, and when more than one, write out full alkyl or aryl name with a di or a tri ie 1,2,3 butanetriol

    • but it is common not IUPAC
  26. Hydrogen bonds:
    • not real "bonds"
    • very strong intermolecular force that has a great effect on physical properties of alcohols (alcohols have higher BPs because of this)

  27. Soluable alcohols have ______ carbons.
    1-3; can disolve because of the hydrogen bonds unlike alkanes
  28. As length of hydrocarbon chain increases, _________ decreases.
  29. _________ is insoluable in water.
    1-decanol, because the chain is non-polar while the OH is polar
  30. Properties of alcohol +ether boiling points:
    • much higher than corrosponding alkanes because of hydrogen bonding
    • the more OH groups, the more H bonds, the higher the BP

    • similar mass BP comparison:
    • alkane<ethers<alcohols<diols<triols< ect.
    • alkanes have non-polar H bonding, goes up from there

  38. hydration:
    • alkene +H2O----> alcohol
    • acid catalyst such as H2SO4 or just write H+
    • uses Markavnikov's rule (H goes with his friends)
  39. dehydration
    • 2 types, both use H2SO4 (sulfuric acid) as a catalyst
    • 1) alcohol--->alkene + H2O when you have excess acid (H2SO4)
    • 2) alcohol--->ether + H2O when you have excess alcohol (still have catalyst of H2SO4)
  40. oxidation
    • results depend on if alcohol is primary, secondary, or tertiary
    • oxidizing agents can be KMnO4 or K2Cr2O7 (potassium dichromate)
    • H+ (acid) catalyst
    • put oxidizing agent over catalyst ---->
    • if   =O is on end, it's an aldehyde
    • if   =O is on a sec. carbon, it's a ketone
  41. catalysts for hydration, dehydration, oxidation (and oxidizing agent for this one)?
    • hydration: H+ such as H2SO4
    • dehydration: H2SO4
    • oxidation: H+ cat., oxidizing agents can be KMnO4 and K2Cr2O7
