Question

18 question (1 point) complete the fischer projection that matches the following dash - wedge structure by dragging the correct group to the correct location. 1st attempt see periodic table

Explanation:

Step1: Recall Fischer - projection rules

In Fischer projections, horizontal bonds are wedges (coming out of the plane) and vertical bonds are dashes (going into the plane). Analyze the dash - wedge structure to determine the relative positions of the groups.

Step2: Identify the top - most chiral center

Starting from the carbonyl end, for the top - most chiral center with the $-OH$ group, in the dash - wedge structure, the $-OH$ is on a wedge. In the Fischer projection, it should be on the horizontal line.

Step3: Identify other groups

For the second chiral center, the $-Cl$ and $-CN$ groups need to be placed according to their relative spatial orientation in the dash - wedge structure. The phenyl ($Ph$) group and other substituents are also placed based on the spatial arrangement.

Step4: Place the groups in the Fischer projection

Place the $-OH$, $-H$, $-CH_3$, $-Cl$, $-CN$, and $-Ph$ groups in the correct positions on the Fischer projection framework.

Answer:

Without the actual correct placement shown in the answer options, a specific answer cannot be given. But the process involves carefully analyzing the spatial orientation of groups in the dash - wedge structure and correctly translating them to the Fischer projection using the rules of horizontal = wedge and vertical = dash for the bonds to the chiral centers.
