Answer 1

Axial up: leaving the plane HOH 20 to H HOH 2 Н . Do Equator down: below the plane [(3S)-oxan-3-yl]methanol Priority of the groups HO: The curved arrow drawn from position 1 to location 2 and then to position 3 rotates counterclockwise, the configuration is classified as S.

JAxial up: leaving the plane HH 1 3 Axial down below the plane CH3 (2R,3R)-3-methyloxan-2-ol Priority of the groups 1 2 он CZY.H— DEE The curved arrow drawn from position 1 to location 2 and then to position 3 rotates clockwise (turn is clockwise), the configuration is classified R. "сна OH IH C-34 CH3 Priority of the groups The curved arrow drawn from position 1 to location 2 and then to position 3 rotates clockwise (turn is clockwise), the configuration is classified R.
