WebTranscribed image text: Remove one hydrogen atom from C_1 the hexane model, and one H atom plus its bond from C_6. Bend the carbon chain around and join C_1 to C_6 to make cyclohexane. Mentally designate one carbon as C_1. Place the model in the chair conformation by tipping C_1 up and C_4 down. Check the conformation with the instructor.

WebJun 21, 2024 · Conformations of Cyclohexane. A planar structure for cyclohexane is clearly improbable. The bond angles would necessarily be 120º, 10.5º larger than the ideal tetrahedral angle. Also, every carbon-hydrogen bond in such a structure would be eclipsed. The resulting angle and eclipsing strains would severely destabilize this structure. Webone factor involved in the slightly lower energy conformation of twisted boat compared to boat in cyclohexane is fewer unfavorable steric factors in the twisted boat in the boat conformation of cyclohexane, the "flagpole" hydrogens are located on the C-1 and C-4 listing the conformations of cyclohexane in order of increasing energy

WebOther than that, the two hydrogen atoms on C1 and C4 are very close to each other and cause steric strain. This is also called the “flagpole” interaction of the boat conformation.
