Chair Interactive Tutorial

  • Updated

Welcome to the Chair Drawing tutorial!

This article will walk you through using the Chair Interactive and Chair "Flip" setting. If they haven't, you may want to ask your instructor to assign the identical tutorial for your course. That version will allow you to follow along with these steps directly.

 

About Chair Flips

In a cyclohexane chair flip (or ring-flip) the carbon skeleton undergoes inversion with respect to a plane resulting in “flipping” of substituents in the following pattern:

  • all equatorial substituents become axial
  • all axial substituents become equatorial
  • all substituents will maintain the direction they are facing
  • substituents that are “up” remain “up”
  • substituents that are “down” remain "down"

Example Question

In this example question, your goal is to draw and submit the conformation B. Conformer B is the cyclohexane chair flip (or ring-flip) of Conformer A. In this question both versions are shown, but not all questions will show both versions. To see the example images in questions, scroll down from the question statement. If there is an example, clicking the image will zoom in on the structure.

In a chair flip question, the user scrolls down to an example image, then clicks to bring up a zoomed in version, pans by dragging, and zooms in more with plus and minus signs.

 

To draw Conformer B, start by selecting the proper conformation of the cyclohexane ring using the “Flip” button. If the question has multiple drawing areas, make sure to select the correct one to begin drawing. Note that if you began drawing before flipping, you will have to start over as the flip clears the diagram.

The user selects the drawing area that is below the question statement and example images. The user then selects the Flip button, which brings up a warning that all drawn items will be cleared. They click accept and the drawing flips.

 

Next, add in the substituents to the proper location on the flipped ring by clicking on the light bond areas to fill them in. If needed, then select the correct element on the Atoms, Bonds and Rings area. 
The user selects the correct bond locations that are dimmed out to make them active parts of the drawing. They then select the functional groups to match those required by the question.
