Question 1 of 4NEET 2014

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

Question 1 of 9

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?
