Chapter 28: Question 28.37 (page 1147)

Convert each ball-and-stick model to a Fischer projection.

(a.)

(b.)

Short Answer

Expert verified

Answer

(a.) Fischer Projection formula of compound a.

(b.) Fischer Projection formula of compound b.

Step by step solution

01

Ball and Stick conformation

It represents the most staggered conformation. To convert it into Fischer projection, it should be converted into less stable eclipsed conformation.

The following steps are followed:

  • Redraw the model as a skeletal structure and rotate it to place the carbonyl group at the top.
  • Convert the staggard form to eclipsed form.
  • Redraw the structure into wedge form.
  • Then draw Fischer projection formula from it.
