  1. Question 1

    Q1. When dry crystalline glucose is dissolved in water, the molecule undergoes a structural rearrangement. What is the predominant form of glucose in solution?

    • A) Open-chain aldehyde form
    • B) Glucopyranose ring form
    • C) Glucofuranose ring form
    • D) Beta-fructofuranose form

    Answer: Glucopyranose ring form

    Explanation: In aqueous solutions, glucose forms a pyranose ring. The open-chain form is rare in solution, and furanose is typically for five-membered rings.
