The dihedral angles in the β-pyranose form of D-ribose are to be identified. Concept introduction: In the chair form of cyclohexane, when two substituents on adjacent carbon atoms are both axial, the dihedral angle between them is 180° . They are anti to each other. When a substituent on one carbon atom is axial and the substituent on adjacent carbon atoms is equatorial, the dihedral angle between them is 60° . They are gauche. When two substituents on adjacent carbon atoms are both equatorial, the dihedral angle between them is 60° . They are gauche.
