chair conformation in organic chem Your OChem exam results will thank you for it. Chair Conformation - Axial vs Equatorial on.
Chair Conformation In Organic Chem, The A-value represents the difference in energy ΔG between a group being axialequatorial on a cyclohexane ring thus as a group gets bigger its A-value increases reflecting the increasingly high energy needed to flip the ring. All cyclohexanes have two chair conformations. Now that we understand the positions of cyclohexane Im actually going to take like five minutes just to teach you how to draw it.
