Statement I: Glucose gives a reddish-brown precipitate with fehling's solution.
Statement I: Reaction of glucose with fehling's solution gives `CuO` and gluconic acid.

A

Statement `I` is true, Statement `II` is true, Statements `II` is the correct explanation of Statement `I`.

B

Statement `I` is true, Statement `II` is true, Statement `II` is not the correct explanation of Statement `I`.

C

Statement `I` is true, Statement `II` is false.

D

Statement `I` is false, Statement `II` is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Statement `I` is true but statement `II` is false because `Cu^(2+)` of Fehling's solution, `[Cu (NH_(3))_(4)]^(2+)(OH)_(2)`, is reduced to `Cu^(+)` to give a red precpitate of `Cu_(2)O`.
`OCH(CHOH)_(4)CH_(2)OH+Cu^(2+)+overset(Θ)OH rarr .^(Θ)OOC-(CHOH)_(4)CH_(2)OH" gluconic acid" +Cu_(2)O+H_(2)O`
