Draw (by hand or with ChemDraw) your structure carefully using the appropriate convention for chair conformation.
4. List all axial and equatorial substituents (including hydrogen atoms).
5. Without breaking any bonds, transform your structure into the other chair shape. Be careful not to rotate the whole molecule.
6. Draw your structure appropriately indicating all the axial substituents and equatorial (including hydrogen atoms).
7. Indicate which of the two chair conformations would be more energetically stable.
