43 multiple choice 2 points the energy barrier for carbon - carbon bond rotation in propane is mainly due to ______. bond strain angle strain steric strain torsion strain previous next
Answer
Answer:
D. torsion strain
Brief Explanations:
In propane, the energy barrier for carbon - carbon bond rotation is mainly due to torsion strain. Torsion strain occurs when eclipsed conformations have electrons in bonds that repel each other more than in staggered conformations. There is no significant bond, angle or steric strain contributing to this rotation barrier compared to torsion strain.
