(a)

Interpretation Introduction

Interpretation:

Each of the given compounds should be classified based on whether it is aldose or ketose and the numbers of carbon atoms presented in it (example: aldopentose).

Concept introduction:

• Carbohydrates are classified into two based on the presence of either aldehyde group or ketone group, that is aldose and ketose.
• Monosaccharides are simple sugars or carbohydrates.
• monosaccharides are classified on the basis of,
  • Presents of aldehyde or ketone group such as aldo or keto.
  • Number of carbon atoms presented in a carbohydrates, triose (3 carbon), tetrose (4 carbon), pentose (5 carbon), hexose (6 carbon) or heptose (7 carbon) (ose indicates the carbohydrates).

To classify: the given compound (a) based on whether it is aldose or ketose and the numbers of carbon atoms presented in it.
