Consider the following statements regarding the chemical properties of D-glucose: A. It gets oxidized to gluconic acid on reaction with bromine water. B. Its pentaacetate derivative reacts with hydroxylamine to form an oxime. C. It gets oxidized to saccharic acid on reaction with nitric acid. D. It yields n-hexane on prolonged heating with HI. E. It gives a positive 2,4-DNP test. Choose the correct option from the gi
Options
- AA, C and D only
- BB, D and E only
- CA, B and C only
- DC, D and E only
Correct answer
A. A, C and D only
Step-by-step solution
Statement A is correct. Bromine water is a mild oxidizing agent that oxidizes the aldehyde group of D-glucose to a carboxylic acid, yielding gluconic acid. Statement B is incorrect. Glucose pentaacetate does not react with hydroxylamine because the aldehyde group is involved in hemiacetal formation and is acetylated, leaving no free carbonyl group. Statement C is correct. Nitric acid is a strong oxidizing agent that oxidizes both the terminal aldehyde and primary alcohol groups of D-glucose to carboxylic acids, for
