  1. Question 1

    Q1. A student performs a Benedict's test on sucrose and maltose. What is the expected difference in their reactivity?

    • A) Both are reducing sugars
    • B) Both are non-reducing sugars
    • C) Sucrose is non-reducing while maltose is reducing
    • D) Sucrose is reducing while maltose is non-reducing

    Answer: Sucrose is non-reducing while maltose is reducing

    Explanation: Sucrose is non-reducing because its glycosidic bond involves both anomeric carbons. Maltose has a free anomeric carbon.
