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

Let us analyze both statements:

Statement I: Fructose does not contain an aldehydic group but still reduces Tollen's reagent.

Fructose is a ketose sugar (contains a keto group, not an aldehyde group). However, in basic medium (Tollen's reagent provides a basic environment), fructose undergoes tautomerism and can reduce Tollen's reagent. This statement is true.

Statement II: In the presence of base, fructose undergoes rearrangement to give glucose.

In basic medium, fructose undergoes Lobry de Bruyn-van Ekenstein transformation, converting to glucose (and mannose) through an enediol intermediate. This statement is true.

Both statements are true, and Statement II correctly explains Statement I (the base in Tollen's reagent converts fructose to glucose, which then reduces the reagent).

The correct answer is Option 1: Both Statement I and Statement II are true.
