324715 \({\text{(A) }}\mathop \rightleftharpoons \limits^{{\text{H}}{{\text{O}}^{\text{ - }}}} {\text{D - Glucose }}\mathop \rightleftharpoons \limits^{{\text{H}}{{\text{O}}^{\text{ - }}}} {\text{D - fructose}}\). Product (A) of above reaction is

1 D-glucose
2 D-Mannose
3 D-talose
4 D-idose
CHXII14:BIOMOLECULES

324716 Assertion :
Glucose and fructose give the same osazone.

During osazone formation stereochemistry at \(\mathrm{C}_{1}\) and \(\mathrm{C}_{2}\) is destroyed.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
