Flagpole hydrogen in cyclohexane
WebThe energy difference between the two conformations comes from strain, called 1,3-diaxial interactions, created when the axial methyl group experiences steric crowding with the two axial hydrogens located on the same side of the cyclohexane ring. WebIf we twist the two flagpole hydrogen’s in the model of the boat conformation of cyclohexane in the opposite direction a new conformation results, which is known as twist-boat conformation. 2. The hydrogen’s on two sets of C—C bonds are not in perfectly eclipsed positions, which relieves the torsional-strain considerably.

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. The two types of strains make the boat conformation have considerably higher energy (about 30 kJ/mol) than the chair conformation. WebOther articles where flagpole hydrogen is discussed: hydrocarbon: Cycloalkanes: …boat brings its two “flagpole” hydrogen atoms to within 1.80 angstroms of each other, far …

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. can baylor beat oklahoma state
