Open Chain Structure

Assertion: Glucose reacts with hydroxylamine to form an oxime and alsoadds a molecule of hydrogen cyanide to give cyanohydrin. Reason: The carbonyl group is present in the open chain structure of glucose.

Explain i. Oxides of nitrogen have open chain structures while those of phosphorus have closed chain or cage structure. Why is it so? IIustrate with one structural example for each type of oxides or The oxides of phosphorus have cage strućtures but not open ones. ii. Elemental phosphorus does not exist as P_2 as N_2

(i) Write one reaction of D-Glucose which cannot be explained by its open chain structure. (ii) What type of linkage is present in Nucleic acids ? (iii) Give one example each for water-soluble vitamins and fat-soluble vitamins ?

Assertion: Glucose reacts with hydroxylamine to form an oxime and alsoadds a molecule of hydrogen cyanide to give cyanohydrin. Reason: The carbonyl group is present in the open chain structure of glucose. (a) Both assertion and reason are correct statements, and reason is the correct explanation of the assertion (b) Both assertion and reason are correct statements, but reason is not the correct explanation of the assertion (c) Assertion is correct, but reason is wrong statement. (d) Assertion is wrong, but reason is correct statement.
