  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?
    CH4+Cl*->Ch3*+HCl
    CH3*+Cl2->Ch3Cl+Cl*
    Propagation, because there is an unpaired electron on both sides.
  3. what free radical step is this?
    Cl*+Cl*->Cl2
    Cl*+CH3->CH3Cl
    CH3*+CH3->C2H6
    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
    Oxidation
  8. Alkenes and Ethers undergo Oxidation, Dehydration, or Esterfication
    Dehydration
  9. Esters undergo oxidation, dehydration or esterfication
    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
    H2SO4
  15. Common catalyst
    Iron Fe, Silver Ag
  16. Low temp and 2 alcohols produce
    ethers
  17. High temperatures and 1 alcohol produces
    alkenes
  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?
    NaOH
  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
