Hydrolysis of an oligosaccharide in the presence of acid yields________________?
Correct answer: C. 2-9 monosaccharide unit
- A. one monosaccharide unit
- B. No monosaccharide unit
- C. 2-9 monosaccharide unit
- D. many monosaccharide
Explanation
On acid hydrolysis, an oligosaccharide breaks into a small number of monosaccharide units, conventionally about 2 to 9 units in this classification. One monosaccharide is a monosaccharide itself, while “many” describes polysaccharides, making those choices category errors.

About Classification of Organic Compounds
Organic compounds are classified by carbon skeleton into open-chain, branched-chain and cyclic compounds, including homocyclic and heterocyclic types. The classification also uses functional groups to distinguish hydrocarbons, halo compounds, alcohols, aldehydes, ketones, carboxylic acids and their derivatives, which is different from naming compounds by IUPAC rules.
