a)

Interpretation Introduction

Interpretation:

The structure of βD-talopyranose is to be drawn.

Concept Introduction:

The structural representation of sugar molecule in cyclic form is known as Haworth projection.  Sugar molecule that has six-membered-ring is known as pyranose and sugar molecule that has five-membered-ring is called furanose.  A sugar molecule in which hydroxyl groups of first and sixth carbon atom are on the same side is known as α sugar, otherwise β sugar.

b)

Interpretation Introduction

Interpretation:

The structure of αD-idopyranose is to be drawn.

Concept Introduction:

The structural representation of sugar molecule in cyclic form is known as Haworth projection. Sugar molecule that has six-membered-ring is known as pyranose and sugar molecule that has five-membered-ring is called furanose. A sugar molecule in which hydroxyl groups of first and sixth carbon atom are on the same side is known as α sugar, otherwise β sugar.

c)

Interpretation Introduction

Interpretation:

The structure of αD-tagatopyranose is to be drawn.

Concept Introduction:

The structural representation of sugar molecule in cyclic form is known as Haworth projection.  Sugar molecule that has six-membered-ring is known as pyranose and sugar molecule that has five-membered-ring is called furanose.  A sugar molecule in which hydroxyl groups of first and sixth carbon atom are on the same side is known as α sugar, otherwise β sugar.

d)

Interpretation Introduction

Interpretation:

The structure of βD-psicofuranose is to be drawn.

Concept Introduction:

The structural representation of sugar molecule in cyclic form is known as Haworth projection.  Sugar molecule that has six-membered-ring is known as pyranose and sugar molecule that has five-membered-ring is called furanose.  A sugar molecule in which hydroxyl groups of first and sixth carbon atom are on the same side is known as α sugar, otherwise β sugar.
