Chapter 3, Problem 3.35P

Interpretation Introduction

Interpretation:

Optical activity of the given compound has to be checked when there is restricted rotation along the central carbon-carbon bond and also optical rotation at elevated temperatures when the rotation becomes less restricted has to be explained.

Concept Introduction:

Atropisomers:

Stereoisomers that occur when rotation around a central carbon-carbon bond is sufficient to allow isolation of individual conformers are called as an atropisomers.
