How will you distinguish 1° and 2° hydroxyl groups present in glucose?

Options

  1. A1° hydroxyl groups are more reactive than 2° hydroxyl groups.
  2. B1° hydroxyl groups are more acidic than 2° hydroxyl groups.
  3. C1 ∘ and 2 ∘ hydroxyl groups present in glucose can be identified by the reaction of glucose with nitric acid.
  4. DDistinguishing between 1° and 2° hydroxyl groups in glucose is not possible as they have similar properties.

Correct answer

C. 1 ∘ and 2 ∘ hydroxyl groups present in glucose can be identified by the reaction of glucose with nitric acid.

Step-by-step solution

Correct Option is : (C) 1 ∘ and 2 ∘ hydroxyl groups present in glucose can be identified by the reaction of glucose with nitric acid. Primary OH group present in glucose easily oxidizes to -COOH group while secondary OH group does not.
