Ring Flip

Postby Dianna Grigorian 1C » Fri Mar 17, 2017 1:44 pm

With the ring flip do the axial up become equatorial up?

Yes, during a ring flip, the axial up's become equatorial up's and vice versa.

Consequently, axial down's will become equatorial down's and vice versa.

Here's a nice diagram of the ring flip of a cyclohexane in chair conformation that illustrates this.

In the diagram which ones are the original axiales and equatorial Im sorry I'm very confused on this topic.

In the ring structure on the left, the blue hydrogen's are either axial up or down. The red hydrogen's are equatorial up or down. After the ring flip, the axial's become equatorial's with respect to the numbered carbons.
