Which of the following statements support the cyclic form for glucose?
(i) It doesn't give Schiff's test.
(ii) It is found to exist in two different crystalline forms.
(iii) It oxidises with nitric acid to give saccharic acid.
(iv) Pentaacetate of glucose doesn't react with hydroxylamine.
- A (i), (ii) and (iv)
- B (i), (iii) and (iv)
- C (ii) and (iii)
- D (i), (ii) and (iii)
Answer & Solution
Correct Answer
(A) (i), (ii) and (iv)
Step-by-step Solution
Detailed explanation
(ii) Anomeric crystalline form (i) do not give Schiff's test, because, - \(\mathrm{CHO}\) group is not free. (iv) Pentaacetate do not react with hydroxylamine, because \(\mathrm{C}=\mathrm{O}\) is not available. So, statements (i), (ii) and (iv) support the cyclic structure of…
