How do you do flip chair conformations?

Answer 1

There is no substitute for a model.

Each equatorial substituent becomes axial when a chair conformer of a 6-membered ring is flipped. Having said that, there is no substitute for creating a model using a molecular model set. This means that in addition to creating the model, you also need to be able to represent the conformer on paper, which is a difficult task that requires practice. Model sets are always allowed in exams.

To perform chair conformations, visualize cyclohexane as a chair with alternating axial and equatorial bonds. Flip by inverting the position of substituents between axial and equatorial positions while maintaining the chair shape.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
