WebTo better demonstrate this alignment of the Br and the β hydrogens, we need to draw the two chair conformations of the cyclohexane: Notice that the anti-periplanar (180o) alignment of the Br and the β hydrogen is only possible when the Br occupies an axial position. None of the β hydrogens appear to be at 180 o to the Br when it is equatorial.

"WebThis chair conformation is the lowest energy conformation for cyclohexane with an overall ring strain of 0 kJ/mol. In this conformation, the carbon-carbon ring bonds are able to assume bonding angles of ~111 o which is very near the optimal tetrahedral 109.5 o so angle strain has been eliminated.

WebFeb 14, 2024 · The chair skeleton of the cyclohexane ring is complete at this stage. Draw lines starting from the corners of the ring, going upwards from the corners pointing up, and going downwards from the corners pointing down, approximately parallel to the axis of the ring. These are six axial bonds shown in green in Figure \(\PageIndex{8}\). WebDec 15, 2024 · Cyclohexane rapidly interconverts between two stable chair conformations because of the ease of bond rotation. The energy barrier is about 45 kJ/mol, and the thermal energies of the molecules at room temperature are great enough to cause about 1 million interconversions to occur per second.
