  2. Alkenes, Alkynes, Functional Groups and Alcohols

  3. Alkenes and Alkynes • Alkenes – hydrocarbons containing at least one double bond between carbon atoms • Alkynes – hydrocarbons containing at least one triple bond between carbon atoms • Unsaturated hydrocarbons – they are not loaded to capacity with hydrogens (alkenes and alkynes) • Alkenes formula: CnH2n • Alkynes formula: CnH2n-2

  4. Alkenes and Alkynes • Ethyne (C2H2) is emitted by ripening bananas to send a message to the other bananas to ripen. • Ethylene (C2H4) is used to ripen fruit. • Why do we put fruit in a paper bag to ripen fruit? • How do shippers keep fruit from ripening too soon?

  5. Naming Alkenes and Alkynes • Base chain is the longest chain containing the double or triple bond • The base ending is –ene for an alkene and –yne for an alkyne • Base chain is numbered to give the double or triple bond the lowest possible number • A number indicating the location of the double or triple bond is inserted before the base name

  6. Practice Naming

  7. Functional Groups • A characteristic atom or group of atoms • A group of organic compounds with the same functional group forms a family

  8. Functional Groups

  9. Alcohols • Organic compounds containing the ―OH functional group • General formula is R-OH • Naming: • Base chain is the longest chain containing the ―OH functional group • Base name ends with ―ol • Base chain is numbered to give the ―OH the lowest possible number • A number indicating the position of the ―OH group is inserted before the base name

  10. Practice Naming
