AThe hydroxyl group is on the third carbon, and the priorities decrease clockwise when the hydrogen is away from the viewer
BThe hydroxyl group is on the second carbon, and the priorities decrease clockwise when the hydrogen is away from the viewer
CThe hydroxyl group is on the second carbon, and the priorities decrease counterclockwise when the hydrogen is away from the viewer
DThe hydroxyl group is on the first carbon, and the priorities decrease clockwise when the hydrogen is away from the viewer
✓ Correct answer: B. The hydroxyl group is on the second carbon, and the priorities decrease clockwise when the hydrogen is away from the viewerIn (R)-2-butanol, the OH group is attached to the second carbon, making it a secondary alcohol. According to the R/S system, the R configuration means that when the lowest priority group (H) is placed away from the viewer, the priorities of the remaining groups decrease in a clockwise direction.
