How will you distinguish 1° and 2° hydroxyl groups present in glucose?
Options
- A1° hydroxyl groups are more reactive than 2° hydroxyl groups.
- B1° hydroxyl groups are more acidic than 2° hydroxyl groups.
- C1 ∘ and 2 ∘ hydroxyl groups present in glucose can be identified by the reaction of glucose with nitric acid.
- 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.
