Question
Chapter 5, Problem 56P
(a)
Interpretation Introduction
Interpretation: The structure of the enantiomer of the arabinose needs to be drawn.
Concept Introduction: Enantiomer has an opposite configuration about the chiral atom.
(b)
Interpretation Introduction
Interpretation: The other enantiomer needs to be drawn.
Concept Introduction: Enantiomer has just opposite configuration about the chiral atom.
(c)
Interpretation Introduction
Interpretation: The structure of diastereomer of arabinose needs to be determined.
Concept Introduction:Diastereomer has the same configuration but opposite configuration about chiral atom.
(d)
Interpretation Introduction
Interpretation: The number of other diastereomer needs to be determined.
Concept Introduction:Diastereomer has just opposite configuration about chiral atom, rest configuration will be same.
(e)
Interpretation Introduction
Interpretation:The rotation of the structure needs to be determined.
Concept Introduction:Rotation is defined as an angle how much the group is rotated about chiral atom of the molecule.
(f)
Interpretation Introduction
Interpretation: The rotation of diastereomer needs to be determined.
Concept Introduction:Diastereomer has rotation about chiral atom only.
(g)
Interpretation Introduction
Interpretation: The optically inactive diastereomer needs to be explained.
Concept Introduction:If a diastereomer has a plane of mirror then it is optically inactive.
