Answer 1

1)Sorbose is a ketohexose

Rhamnose is a aldoketose

Erythrolose is ketobutose

Xylulose is ketopentose

Glucose is aldohexose

2) Glucose is a D - Sugar

Rhamnose is a deoxy sugar

Sorbose is a sugar with 3 stereogenic centres

3) Sorbose has 3 chiral centre

Erythrolose has 1 chiral centre

Xylulose has 2 chiral centre

Rhamnose has 4 chiral centre

Glucose has 4 chiral centre,
