Chapter 5, Problem 5.16YT

Interpretation Introduction

Interpretation:

The position of $\text{-OH }$ groups on C2, C3, and C4 in zigzag conformation in figure $\text{5}.\text{23a}$ and Fischer projection in figure $\text{5}.\text{23b}$ is to be compared, and pattern is to be determined.

Concept introduction:

The bonds on the same side of the carbon chain’s plane in zigzag structure are on the opposite side in a Fischer projection.

The bonds on the opposite side of the carbon chain’s plane in zigzag structure are on the same side in a Fischer projection.
