Which of the following phenomena is NOT explained by the open chain structure of glucose?
Options
- AFormation of pentaacetate of glucose with acetic anhydride.
- BFormation of oxime with hydroxylamine.
- CFormation of silver mirror with Tollen's regent.
- DExistence of and forms of glucose.
Correct answer
D. Existence of and forms of glucose.
Step-by-step solution
Glucose exists in two cyclic forms, and , which are formed by intramolecular hemiacetal formation between the aldehyde group and one of the alcoholic group at C-5 within the molecule. Thus, the open chain structure of glucose does not explain the existence of and forms of glucose.
