Chapter 26.SE, Problem 22VC

Interpretation Introduction

Interpretation:

Depending on the chiral carbon, a molecule is able to shift the plane polarized light towards right or left.

Concept introduction:

If the plane polarized light is shifted to the right by a molecule it is dextrorotatory (D-form) and if the light is shifted to the left it is levorotatory (L-form). Usually, most of the α-amino acids are of L-form.

To determine:

Whether the given structure has L form or D-form and to identify the structure.
