Convert each ball-and-stick model to a Fischer projection.
a.
b. 
(a)
Interpretation: The given ball-and-stick model is to be converted into Fischer projection.
Concept introduction: In Fischer projection formula, the horizontal and vertical line represents the bonds that are present above and below the plane, respectively. The verticals bonds are represented as dashed wedge and horizontal bonds as dark wedge.
Answer to Problem 36P
The Fischer projection of given ball and stick model is shown below.
Figure 1
Explanation of Solution
The ball and stick model of given compound is,
