Question

Select the correct wedge dash projection of following compound.

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

The compound given is in Fischer project. We have to change it to wedge dash model.
Steps to convert Fischer to wedge projection:
1. The vertical line in fischer should project upward and horizontal line should be projected downward as shown below.

2. Now view the molecule from left hand side, you can see Cl atom is projected toward you and OH group is projected away from you and the $C{H}_3$ group and H are in plane like V shape.
3. Groups seen in plane are drawn in normal line and group projected toward you is drawn in wedge and group projected away from you is drawn in dashed. Thus the molecule structure is,
