Presentation Transcript

  1. Chemistry Chapter 22 Notes #3 Alkenes and Alkynes

  2. review • Draw the following • Nonane • 2,4,7 trimethyl nonane • 2,3 dimethyl 5 propyl decane • 4 isopropyl heptane • Methylcyclopentane • 1,3 diethyl cyclobutane • 1,2,2,4 tetramethylhexane

  3. Alkenes • Unsaturated Hydrocarbons • At least one double bond in the carbon chain • More reactive than alkanes • Formula • CnH2n • To figure out number of Hydrogen's • Names end in –ene • Ex. Ethene

  4. Alkene Examples • Butene • 3,4 dimethyl 2pentene • Why is it numbered that way? • 1,5 octadiene • 4 butyl cyclohexene

  5. Alkynes • Unsaturated Hydrocarbons • At least one triple bond in the carbon chain • More reactive than alkanes and alkenes • Formula • CnH2n - 2 • To figure out number of Hydrogen's • Names end in –yne • Ex. Ethyne

  6. Alkyne Examples • Butyne • 4-heptyne • 4ethyl, 2 methyl, 1 hexyne
