Interpretation Introduction

Interpretation:

The carbohydrate is to be identified from among the given molecules.

Concept Introduction:

Carbohydrates are polyhydroxy aldehydes or ketones, or their derivatives.

Straight-chain carbohydrates are characterized by the presence of a $\text{C=O}$ group, $\text{OH}$ groups along the chain, and a ${\text{CH}}_{\text{2}}\text{OH}$ group.

Ring-form carbohydrates are characterized by the presence of a ring containing carbon atoms and one oxygen atom. The ring also contains $\text{OH}$ and ${\text{CH}}_{\text{2}}\text{OH}$ groups.
