Chapter 15, Problem 15.61P
Interpretation Introduction

(a)

Interpretation:

Whether lactose is dextrorotatory or levorotatory compound should be determined.

Concept Introduction:

Chiral or optically active molecules can rotate plane-polarized light either clockwise or counter clockwise. If plane-polarized light is rotated clockwise then it is known as dextrorotatory and for counter clockwise rotation it is known as levorotatory.

Interpretation Introduction

(b)

Interpretation:

Specific rotation of the enantiomer of lactose should be determined.

Concept Introduction:

Enantiomers rotate the plane-polarized light in opposite directions by same angle.

Interpretation Introduction

(c)

Interpretation:

The amount of lactose enantiomer dissolved in water should be determined.

Concept Introduction:

Physical properties of enantiomers are similar except the direction of optical activity. Solubility, melting point, boiling points are similar.
