Cyclohexane chair axial equatorial
WebCYCLOHEXANE CONFORMATIONAL ENERGY DIAGRAM Axial and Equatorial Bonds in Cyclohexane Note that in chair cyclohexane, there are two different types of C-H bonds, and thus two chemically different types of hydrogens. The C-H bonds which point vertically upward or downward are called axial. WebFeb 20, 2011 · He says cyclohexane is in equilibrium between the two chair-shapes. Before he put the hydrogens on there, I would have said the two chair shapes were equivalent. You could get from …
