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.

Describe the principle of resonance and give a set of Lewis Structures to illustrate your explanation.
Don't used hand raiting
It is not unexpected that the methoxyl substituent on a cyclohexane ring prefers to adopt the equatorial conformation. OMe H A G₂ = +0.6 kcal/mol OMe What is unexpected is that the closely related 2-methoxytetrahydropyran prefers the axial conformation: H H OMe OMe A Gp=-0.6 kcal/mol Methoxy: CH3O group Please be specific and clearly write the reason why this is observed. This effect that provides stabilization of the axial OCH 3 group in this molecule is called the anomeric effect. [Recall in the way of example, the staggered conformer of ethane is more stable than eclipsed owing to bonding MO interacting with anti-bonding MO...]
