Question
Chapter 15, Problem 56P
Interpretation Introduction
(a)
Interpretation:
The specific rotation of the enantiomer of lactose 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:
Boiling point comparison should be done for enantiomers of Taxol.
Concept Introduction:
Physical properties of enantiomers are similar except the direction of optical activity. Solubility, melting point, boiling points are similar in enantiomers.
Interpretation Introduction
(c)
Interpretation:
The solubility of Taxol needs to be compared to its enantiomer.
Concept Introduction:
Physical properties of enantiomers are similar except the direction of optical activity. Solubility, melting point, boiling points are similar in enantiomers.
