(a)

Interpretation Introduction

To draw: The chair conformation of β-D-mannopyranose.

Interpretation: The chair conformation of β-D-mannopyranose is to be drawn.

Concept introduction: Cyclic monosaccharides are drawn with the help of Fisher projection. The groups on the right side of fisher projection are projected downwards in the cyclic structure while groups on the left side are projected upwards. In Haworth projection or chair conformation, oxygen is present at the back, right-hand corner with C1 at the far right.

(b)

Interpretation Introduction

To draw: The chair conformation of α-D-allopyranose.

Interpretation: The chair conformation of α-D-allopyranose is to be drawn.

Concept introduction: Cyclic monosaccharides are drawn with the help of Fisher projection. The groups on the right side of fisher projection are projected downwards in the cyclic structure while groups on the left side are projected upwards. In Haworth projection or chair conformation, oxygen is present at the back, right-hand corner with C1 at the far right.

(c)

Interpretation Introduction

To draw: The chair conformation of β-D-galactopyranose.

Interpretation: The chair conformation of β-D-galactopyranose is to be drawn.
