Strains

Postby DanielLee3H » Mon Mar 13, 2017 1:09 am

Just to clarify, Steric strains are high in energy due to the instability caused by the physical presence of multiple atoms in a limited area, while torsional strains are caused by repulsion between electron dense clouds of hydrogens when eclipsed? Isn't that essentially the same thing?

You can refer to this to see the difference between the two strains!

But basically, I believe that torsional strains are steric strains that occurs when there are eclipsed or gauche interactions, so they are similar to each other.

It may seem as though steric and torsional strain are very similar, which they in a way are, but the most important distinction between the two is that steric strain is due to actual/physical interaction between atoms in a molecule when they are close to each other while torsional strain is caused by "non-touching" interaction. So you can technically say that steric strain is a factor when atoms are REALLY close to each other.
