  1. Are you ready for some science?

  2. Alkyl Halides -----Kiany Louis Jimmy

  3. Today’s Objectives • After today's class, you will be able to know: • What is the Alkyl Halides!!!!! • How to name the Alkyl Halides (super easy!!!) • Some other properties of Alkyl Halides!!!!!

  4. Chlorofluorocarbons(CFCs) Anorganic compoundthat contains carbon,chlorine, andfluorine Physical properties: • - colorless • relatively odorless • low toxicity • - can be dissolved in water

  5. Brainstorm What kinds of things do people use CFCs to do in our daily life?

  6. Explain it in a simple way An organic compound containing at least one carbonhalogen • bond (C-X) • X (F, Cl, Br, I) replaces H Can contain many C-X bonds Properties and some uses • Fire-resistant solvents • Refrigerants

  7. How to name it? http://v.youku.com/v_show/id_XNTIxMzkzMDcy.html Name it in the same manner used for alkyl groups. F-fluoro Cl-chloro B-bromo(the general term for an attached halogen atom is a "halo" group).

  8. Let me tell you how to do this • examples: Candy time! • Are you ready? Are you sure? Ready? Set? Go!! CH3-Cl = USE YOUR BRAIN! chloromethane

  9. Naming Alkyl Halides • Name is based on longest carbon chain • (Contains double or triple bond if present) • Number from end nearest any substituent (alkyl orhalogen)

  10. Naming with Multiple Halides • if more than one of the same kind of halogen is present, use the prefixes di,tri, etc.

  11. if a compound contains both alkyl and halo groups, list the attached groups in alphabetical order. Start numbering the end which gives the lowest set of number.

  12. Naming if Two Halides or Alkyl Are EquallyDistant from Ends of Chain • Begin at the end nearer the substituent whose namecomes first in the alphabet.

  13. THE HARDEST 截图 Hard? Easy. Normal! - - CH2F CHCI2 CHI2 Absolutely NO!!!! Can we do this? The reason why we can't do this is because there is no place for another carbon to attach to the carbon that has already existed. let's me show you a diagram. CI H No space for another C C F C H H CI

  14. Question Time ! Naming 1.CH3-CHBr-CHF-CH2-CH3 Ans:2-bromo-3fluoropentane 2.CHI2-CH2-CH2-CH2-CHF-CBr2-CH2I Ans: 2-dibrome-3-fluoro-1,6,6-triindohexane 3.CH3-CHCH2CH3-CH2-CH2-CHCl-CH2-CHI2 Ans:3-chloro-1,1-diindo-6-ethylheptane

  15. Ans: 1-chloro-2-flouro-3,3-diindocyclopentane CH2 • 4 CH-CI H2C I2C CH-F

  16. Properties of Alkyl Halides • 1. Will Alkyl Halides dissolve in water? • 2. Whether Alkyl Halides are polar-compound or nonpolar-compound?
