Alkene Isomers#

Investigate the stability of alkene isomers due to steric interactions.

Task#

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.

Examples:

  • 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.
