Substituted Cyclohexanes

The substituted cyclohexanes are again displayed initially as "wireframe" models. Click the appropriate buttons to get "space-filling" models (better for seeing where atoms are close enough together to repel one another), or to highlight specific sets of atoms. Rotate the models using the mouse; you can return each model to its original orientation (and colors) at any time by clicking the "Reset" button.

Exercises to do with these models:

  • View each molecule as a wireframe model, and practice drawing it on paper - then change the orientation and draw it again. Practice until you are able to recognize different drawings (orientations) of the same conformation.

  • Identify the interactions in each conformation before clicking the button that will highlight them.

  • Compare the spacefilling model of each conformation. Can you see which one is less stable, and why?

(Note: Sets of H's have been color-coded for clarity.)
