Chapter 5.4, Problem 20ATS
Interpretation Introduction

Interpretation:

To calculate the specific rotation of given molecules.

Concept Introduction:

Specific rotation: The observed rotation of optically active molecule such as non-superimposable molecule measured using the polarimeter, depends on the experimental conditions and therefore is not a characteristic property of compound.

The specific rotation can be calculated by using the formula given below.

Specificrotation=[α]λT=αc×l

alpha (α) represents the observed rotation measured with a polarimeter. l represents the length of the sample tube.     C is the concentration of a solution of a pure sample.λ is the wave length of the light.

To identify: Solving the observed rotation of given molecule.
