Question
Chapter 16, Problem 16.47SP
Interpretation Introduction
Interpretation: The information regarding the poor optical activity of hexahelicene due to the presence of
Concept introduction: The extent of chiral molecules to rotate the plane of polarized light is known as optical rotataion. It is measured using a polarimeter tube. It is dependent on the concentration of the solution, path length,
To determine: An explanation corresponding to optical activity of hexahelicene and large rotation.
