(a)

Interpretation Introduction

Interpretation:The observed specific rotation of table sugar should be calculated and whether any information about the optical rotation for the enantiomer of natural sucrose is obtained from this calculation or not is to be determined.

Concept introduction:The formula to calculate specific rotation is given as follows:

  [α]=αl×c

Where,

  • α is observed optical rotation.
  • l is path length of cell in decimeters.
  • c us concentration in g/mL .

The enantiomers are identical chemical compounds that have a mirror-image relationship to each other. The two enantiomers rotate the plane-polarized in opposite direction. This indicates one is dextrorotatory and one is levorotatory.

(b)

Interpretation Introduction

Interpretation: The observed specific rotation of ()-2-hydroxypropanoic acid is to be determined.

Concept introduction:The formula to calculate observed rotation from specific rotation is given as follows:

  α=[α]×l×c

Where,

  • α is observed optical rotation.
  • l is path length of cell in decimeters.
  • c us concentration in g/mL .
