Chair Like Conformation, Alternate your axial substituents up and down all the way around your cyclohexane. The two red hydrogens called flagpole hydrogens approach each other too closely and cause some steric strain. Next add a downward-pointing V tip to one end this is the tail of the chair.

The chair conformation is a six-membered ring in which atoms 2 3 5 and 6 lie in the same plane atom 1 lies above the plane and atom 4 lies below the plane. In this conformation there is no torsional strain at all and as we shall see later no strain of any kind. Like the chair conformation all of the C C C bond angles of the boat conformation are 1095 so it has no angle strain. This video is about Stereoisomerism of Chair Conformation. A discrete hexanuclear zirconium metallocycle has been synthesized isolated and characterized by single-crystal X-ray diffraction.
Every carbon on the chair conformation has 1.
The tert-butyl group needs to be placed in the equatorial bond as it is the lowest energy or highest stability conformation. The chair conformation is a six-membered ring in which atoms 2 3 5 and 6 lie in the same plane atom 1 lies above the plane and atom 4 lies below the plane. However keep in mind that the geometry of the cyclohexane needs to be.

For each chair conformer add the energy of all the groups on axial position. Looking at the glucopyranose from above you now can easily draw the chair conformation for it in a general form. On the right you may notice that the red-colored hydrogen atoms are now in a different chemical environment. At 25 C 9999 of all molecules in a cyclohexane solution adopt this conformation. At room temperature theres enough energy for the molecule to contort and achieve another chair conformation. Chair structures are considered to be conformationally mobile meaning they are flexible not as much so as a straight chain alkane but more so than any of the other smaller rings and because of this flexibility they flip from one possible chair to the other possible chair.
