Isomer alkuna

  1. 1. <ul><li>The members of the Group: </li></ul><ul><li>Ahadiya Rosalina </li></ul><ul><li>Aji Pambudi </li></ul><ul><li>Bagus Rayi Laksana </li></ul><ul><li>Dede Dwi Utari </li></ul>
  2. 2. <ul><li>Isomer in alkynes includes the structural isomer and position isomer but alkyne have no geometical isomer. The isomer in alkynes begins from Butyne. </li></ul><ul><li>The isomer of butyne: </li></ul><ul><li>CH C – CH 2 – CH 3 (1-Butyne) </li></ul><ul><li>CH 3 – C C – CH 3 (2-Butyne) </li></ul>
  3. 3. <ul><li>Isomer of PENTYNE: </li></ul><ul><li>CH C – CH2 – CH2 – CH3 (1-PENTYNE) </li></ul><ul><li>CH3 – C C – CH2 – CH3 (2-PENTYNE) </li></ul><ul><li>CH C – CH – CH3 (3 methyl-1 Butyne) </li></ul><ul><li> CH3 </li></ul><ul><li>Isomer of hexyne: </li></ul><ul><li>CH C – CH2 – CH2 – CH2 – CH3 </li></ul><ul><li>(1-hexyne) </li></ul><ul><li>CH3 – C C – CH2 – CH2 – CH3 </li></ul><ul><li>(2-hexyne) </li></ul>
  4. 4. <ul><li>CH3 – CH2 – C C – CH2 – CH3 </li></ul><ul><li>(3-hexyne) </li></ul><ul><li>CH C – CH – CH2 – CH3 </li></ul><ul><li> CH3 </li></ul><ul><li>(3 methyl-1 PENTYNE) </li></ul><ul><li>CH C – CH2 – CH – CH3 </li></ul><ul><li> CH3 </li></ul><ul><li>(4 methyl-1 PENTYNE) </li></ul>
  5. 5. <ul><li>CH3 – C C – CH – CH3 </li></ul><ul><li> CH3 </li></ul><ul><li>(4 methyl-2 PENTYNE) </li></ul><ul><li>CH3 </li></ul><ul><li>CH C – C – CH3 </li></ul><ul><li>CH3 </li></ul><ul><li>(3,3 dimethyl – 1 butyne) </li></ul>
  6. 6. <ul><li>The Properties of Alkynes are devided into physycal and chemical properties. </li></ul><ul><li>The chemical properties of alkyne are reaction. </li></ul><ul><li>The physical properties or boisome alkynes are presented bellow: </li></ul>Name Boiling Point Etyne -75 o c Propyne -23 o c 1-Butyne 8,1 o c 2-Butyne 27 o c
  7. 7. <ul><li>Reaction on the alkyne is similar to the one in alkene. However, alkynes need reactant twice bigger than alkenes to prove that there is an unsatured bond on the molecule. Reactant of alkyne not only Hydrogen but also Hydrogen Halides and Halogens. </li></ul><ul><li>The examples: </li></ul><ul><li>CH3 – C CH + H2 -> CH3 – CH CH2 </li></ul><ul><li>(1 propuna + H2) -> 1 propena </li></ul><ul><li>CH3 – CH CH2 + H2 -> CH3 – CH2 – CH3 </li></ul><ul><li>(1 Propena + H2) -> n-Propana </li></ul>
