Chair conformation for The most stable conformation for cyclohexane is the chair conformation. Clockwise or counterclockwise doesnt matter as long as you use the same direction for both molecules.
Chair Conformation For, So for 1R-33-dichlorocyclohexanol the two chair conformations are. In the first conformer we have two chlorines in axial positions so the total steric strain is. Most of the time the structure exists in what is called the chair conformation.

Chair Conformations Examples. In the first conformer we have two chlorines in axial positions so the total steric strain is. Draw BOTH chairs and compare energy and stability. All bonds to hydrogen atoms on adjacent carbon atoms are staggered and therefore torsional strain is minimized. 1 2 2 1 3 3 4 4 5 6 6 5 OH H Cl Cl OH Cl Cl H These conformations can then be used to evaluate the absolute or relative steric strain energies.
In this conformation angle strain is eliminated because all internal bond angles are equal to 1095.
Circle the more stable one. If the tert-butyl group is placed in the axial bond then the chair has the highest energy or the least stable conformation. The definition of chair conformation is the lowest energy conformation for cyclohexane in which all bond angles are fairly close to 1095 and all hydrogen atoms are staggered. Draw the lowest energy chair conformation for each of the following cyclohexane structures. This conformation is called the chair because it looks sort of like a reclining lounge chair as shown here.

If the tert-butyl group is placed in the axial bond then the chair has the highest energy or the least stable conformation. Draw the ring flip for each of the following chair conformations. 1 2 2 1 3 3 4 4 5 6 6 5 OH H Cl Cl OH Cl Cl H These conformations can then be used to evaluate the absolute or relative steric strain energies. Before deciding whether or not this is the most stable chair conformation you must draw the chair flip conformation as well. As taught in this Tutorial Video.

Chair conformation is the term used in organic chemistry that represents the chair-like structure of a carbon ring consisting of six carbon atoms. Clockwise or counterclockwise doesnt matter as long as you use the same direction for both molecules. Draw BOTH chairs and compare energy and stability. Actually these bonds are a bit wobbly too enough for the carbons to wobble between boat and chair conformations on occasion. Now you draw the first chair conformation for the molecule by placing the ethyl group in UP position on an axial bond and the methyl group in DOWN position on an axial bond as well.
