  1. what free radical step is this?

    Cl2+UV light->2Cl*
    * is an unpaired electron
    Initiation, because there are 2 unpaired electrons on the right side of the reaction.
  2. what free radical step is this?
    Propagation, because there is an unpaired electron on both sides.
  3. what free radical step is this?
    Termination, because there are 2 unpaired electrons on the left.
  4. Halogenation where R is a alkyl group and H is  hydrogen atom (RH), and X is Bromine or Chlorien.
    1) Formula for Halogenation?
    2) Type of reaction?
    • 1) RH+X2->RX+HX
    • (CH3CH3+Cl2->CH3CH2Cl+HCl
    • 2) Substitution reaction
  5. 1) Dehydrogenation is where _____
    2) Formula?
    3) Type of reaction?
    • 1) where hydrogen is lost during the process (heat applied)
    • 2) CnH2n+2----heat700C-->CnH2n+H2
    • 3) elimination reaction
  6. 1) Cracking is...
    2) formula
    • 1) Breaking large molecules into small ones by adding a catalyst
    • 2) -Δcatalyst->
  7. Aldehydes, Keytones, and carboxylic acids undergo: Oxidation, Dehydration or Exterficatin
  8. Alkenes and Ethers undergo Oxidation, Dehydration, or Esterfication
  9. Esters undergo oxidation, dehydration or esterfication
  10. When alcohol is mixed with a strong base like H2SO4 it makes
    an oxonium ion acting like an acid
  11. When alcohol is mixed with +2Na it makes
    an alkoxide ion decreasing reactivity because of increased molar mass.  -OH plays a less significant part.
  12. Saytzeff's rule in the conversion of alcohols to Ethers
    It prefers the location of the alkene with the most alkyl groups attached to the double-bonded carbon.
  13. 3 Common oxidizing agents
    • 1) KMnO4 potassium permangnate
    • 2) K2Cr2O7 Potassium dichromate
    • 3) O2 peroxide
  14. Common dehydrant
  15. Common catalyst
    Iron Fe, Silver Ag
  16. Low temp and 2 alcohols produce
  17. High temperatures and 1 alcohol produces
  18. 3 ways to make alcohol
    • 1) Hydrolysis of ester
    • 2) alkaline hydrolysis of alkyle halide (1 and 2 degree only)
    • 3) Catalytic reduction of aldehydes and ketones to produce primary and secondary alcohols.
  19. Formula for hydrolysis of ester
    H+Δ around--->
  20. Alaline hydrolysis of an alkyle halide (1 and 2 degree) adds what to RX (R=alkyle group, X=bromine/Chlorine?
  21. catalytic reduction of aldehydes and ketones only produce Which (primary secondary tertiary alcohols)?
    Primary and secondary
  22. What's petachlorophenol
    OH phenol with 5 Chlorines attached to a carbon
