(a)

Interpretation Introduction

Interpretation:

Fischer projection for D-galactose has to be drawn.

Concept Introduction:

Fischer projection formula simply uses cross for representing tetrahedral carbon atom.  The carbon atom that is present in the intersection point in cross.  The horizontal bonds means they are coming forward and they are present on wedge bond.  The vertical bonds means they are pointing away and they are present on dashed lines.

(b)

Interpretation Introduction

Interpretation:

Fischer projection for the enantiomer of D-galactose has to be drawn.

Concept Introduction:

Enantiomers are two stereoisomers of a compound that rotate the plane polarized light exactly opposite.  The configuration present in the enantiomers will be exactly opposite to each other.

Fischer projection formula simply uses cross for representing tetrahedral carbon atom.  The carbon atom that is present in the intersection point in cross.  The horizontal bonds means they are coming forward and they are present on wedge bond.  The vertical bonds means they are pointing away and they are present on dashed lines.
