Pairing of Osazones:
Osazones are crystalline compounds that are formed by the reaction of reducing sugars with phenylhydrazine. They have characteristic structures that can be used to identify the sugar involved.
In this question, we are given four pairs of sugars and we need to determine which pairs give the same osazone.
Pair a) D-glucose; D-mannose:
D-glucose and D-mannose are both hexose sugars with the same formula, C6H12O6. They differ only in the configuration of one carbon atom. When these sugars are treated with phenylhydrazine, they will form the same osazone.
Pair b) D-galactose; D-tallose:
D-galactose and D-tallose are also hexose sugars, but they have different structures. When these sugars are treated with phenylhydrazine, they will form different osazones.
Pair c) D-gulose; D-idose:
D-gulose and D-idose are both hexose sugars, but they have different structures. When these sugars are treated with phenylhydrazine, they will form different osazones.
Pair d) D-altrose; D-glucose:
D-altrose and D-glucose are both hexose sugars, but they have different structures. When these sugars are treated with phenylhydrazine, they will form different osazones.
Conclusion:
From the given pairs, only pair a) D-glucose; D-mannose gives the same osazone. The other pairs, b) D-galactose; D-tallose and c) D-gulose; D-idose, give different osazones.
Therefore, the correct answer is option 'A, B, C'.
