Verified step by step guidance

Understand the concept of sugar alcohols: Sugar alcohols are formed by the reduction of the carbonyl group (aldehyde or ketone) in sugars to a hydroxyl group, resulting in an alcohol.

Identify the structure of D-ribose: D-ribose is a pentose sugar with an aldehyde group at the first carbon. Its chemical formula is C₅H₁₀O₅.

Determine the reduction process: Reduction of D-ribose involves converting the aldehyde group at the first carbon into a hydroxyl group, forming a sugar alcohol.

Recognize the naming convention: The sugar alcohol derived from D-ribose is named by replacing the '-ose' suffix with '-itol', indicating it is an alcohol.

Conclude the name of the sugar alcohol: The sugar alcohol produced from the reduction of D-ribose is D-ribitol, as the reduction of the aldehyde group results in the alcohol form.
