Question

Among the following, the compound(s) which produce the same osazone as that obtained from D-glucose, when reacted with phenylhydrazine, is/are

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is A, B

• (A) The structure in option (A) represents a compound that will react similarly to D-glucose and produce the same osazone, due to the presence of an aldehyde group and the configuration of hydroxyl groups on the carbon chain.
• (B) Option (B) also has the appropriate aldehyde group structure and hydroxyl group configuration, similar to D-glucose, which leads to the same osazone formation when reacted with phenylhydrazine.
• (C) Option (C) lacks the necessary aldehyde group and will not yield the same osazone product as D-glucose.
• (D) Option (D) also does not exhibit the same characteristics for osazone formation as D-glucose.

Thus, the correct answers are (A) and (B)
