Alkene Isomers#

Investigate the stability of alkene isomers due to steric interactions.


Build and optimize the geometry of isomeric alkenes and compare their relative energies to confirm empirical rules for evaluating alkene stability: Zaitsef’s rule, cis- vs trans-, isolate vs conjugated dienes.


  • Compare: 1-hexene, 2-hexene (cis and trans), 2-methyl-2-pentene, 2,3-dimethyl-2-butene.

  • Compare: 1,4-pentadiene and 1,3-pentadiene.
