Given are 4 statements related to the chemical properties of Glucose. Identify the two incorrect statements from the following. A. It reacts with Br ₂ (aq) to form Saccharic acid. B. Reacts with Acetic anhydride to form Glucose tetraacetate. C. Reacts with Hydroxylamine to give Glucose oxime. D. It reacts with ammoniacal AgNO ₃ to form ammonium salt of Gluconic acid with deposition of silver.
Options
- AA & C
- BC & D
- CA & B
- DB & D
Correct answer
C. A & B
Step-by-step solution
Glucose reacts with bromine water ( Br ₂ water) to form Gluconic acid, not Saccharic acid. Saccharic acid (glucaric acid) is formed by the oxidation of glucose with concentrated nitric acid. Thus, statement A is incorrect. Glucose reacts with acetic anhydride to form Glucose pentaacetate, not Glucose tetraacetate, because glucose contains five hydroxyl groups. Thus, statement B is incorrect. Glucose reacts with hydroxylamine ( NH ₂ OH ) to form glucose oxime, which is a correct statement. Glucose reacts with Tollen
