- two groups on adjacent carbons whose dihedral angle is about 60
- syncoplanar
- two groups on adjacent carbons whose dihedral angle is 0
- strain
- any factor that destabilizes molecular structure by forcing it to deviate from optimum bonding geometry
- torsional strain
- increase in energy by repulsion of electrons when brought into close proximity of electrons on another atom or group (syncoplanar example)
