Solution

The correct option is D the same constitution and same configuration at C-3, C-4, C-5 and C-6, but different constitution and configuration at C-1 and C-2, which becomes identical after osazone formation.
Same osazone derivative is obtained in case of D-glucose, D-mannose and D-fructose due to the same constitution and same configuration at C-3, C-4, C-5 and C-6, but different constitution and configuration at C-1 and C-2, which becomes identical after osazone formation.

Q. Assertion :When the ketohexose, D() fructose is treated with phenyl hydrazine it produces an osazone that is identical with the one prepared from either D-(+) glucose or D-(+) mannose. Reason: Sugars forming same osazone have different configuration

C_{1}

and

C_{2}

that are involved in osazone formation, the rest four carbon atoms (

C_{3}, C_{4}, C_{5} a n d C_{6}

are same) are identical. Since all belongs to D-Family hence the configuration of last but one asymmetric carbon atom would be the same
