Question

Quizplus · Accepted Answer

In the Fischer projection, the groups on the vertical line are assumed to be behind the plane of the paper, while the groups on the horizontal line are assumed to be in front of the plane of the paper. The correct wedge/dash drawing for the Fischer projection should show this stereochemistry. The only option that correctly shows this stereochemistry is option II. Option I and IV do not correctly show the stereochemistry, and option III shows the correct stereochemistry but with the wrong orientation. Therefore, the best choice is B.
