Vedclass · Answer

(A) Glucose and fructose differ only in the configuration at $C_1$ and $C_2$ atoms. During the reaction with excess phenylhydrazine,the $C_1$ and $C_2$ atoms are involved in the formation of the osazone structure. Since the stereochemistry at $C_3, C_4, C_5,$ and $C_6$ remains identical in both glucose and fructose,they yield the same osazone product. Therefore,the Reason correctly explains the Assertion.

Assertion: Glucose and fructose give the same osazone.
Reason: During osazone formation,stereochemistry only at $C_1$ and $C_2$ is destroyed.
