WebAug 19, 2024 · The boat conformation is less stable than the chair form for two major reasons. The boat conformation has unfavorable steric interactions between a pair of 1,4 hydrogens (the so-called "flagpole" hydrogens) that are forced to be very close together (1.83Å). This steric hindrance creates a repulsion energy of about 12 kJ/mol. An … im having trouble getting my coins off kucoin

The boat conformation comes from partial C-C bond rotations (only flipping one carbon up to convert the chair to a boat) of the chair conformation, and all the carbons still have 109.5º bond angles, so there are no angle strains. However, the hydrogens on the base of the boat are all in eclipsed ... WebThe second gauche interaction can be seen by looking from the bottom left corner: So, the 1,3-diaxial notation is the most common way we refer to the gauche interactions of axial groups in the chair conformations.
