Carbohydrate Chemical Reactions
Explore key reactions of carbohydrates such as mutarotation, osazone formation, oxime formation, and hydrolysis.
Why this shows up in the exam
Understanding these reactions helps in solving mechanism and identification questions.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
D(+)-glucose reacts with hydroxyl amine and yields an oxime. The structure of the oxime would be CH=NOH | H-C-OH | HO-C-H | HO-C-H | H-C-OH | CH₂OH CH=NOH | HO-C-H | HO-C-H | H-C-OH | H-C-OH | CH₂OH CH=NOH | HO-C-H | H-C-OH | H-C-OH | CH₂OH CH=NOH | H-C-OH | H-C-OH | HO-C-H | H-C-OH | CH₂OH
Push further
More challenging9 harder questions built from the past papers above — a step up in difficulty, with distractors designed so you can't get there by elimination. Written and checked by our reviewers, not from a real paper.
Consider D-galactose, which has the following open-chain Fischer projection: CHO at C1, H-C-OH at C2, HO-C-H at C3, HO-C-H at C4, H-C-OH at C5, and CH₂OH at C6. What is the structure of the product formed when D-galactose reacts with hydroxylamine?
