WebFigure 4.3a Boat conformation of cyclohexane. 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 ... WebChair Half-chair Boat Twist-boat Flagpole hydrogens are not found in any cyclohexane conformers This problem has been solved!
