WebFeb 14, 2024 · The bulky group at the axial position has steric repulsion with the other two axial \(\ce{H's}\) on the same face of the ring, called 1,3-diaxial interaction, as illustrated in Fig. 11. Therefore, the chair conformation with the bulky group at equatorial position is more stable and more predominant at equilibrium than its flipped form with the ...
