Q. Given below are two statements: Statement I: Fructose does not contain an aldehydic group but still reduces Tollen's reagent Statement II: In the presence of base, fructose undergoes rearrangement to give glucose. In the light of the above statements, choose the correct answer from the options given below
A) Both Statement I and Statement II are true
B) Both Statement I and Statement II are false
C) Statement I is true but Statement II is false
D) Statement I is true but Statement II is false
Explanation
[Solution by Dr. Abubacker] Fructose is a ketose, but in basic medium it undergoes enolisation (via an enediol) and rearranges to glucose and mannose, which contain the aldehyde group and so reduce Tollens' reagent. Both statements are true. Answer (1).
