Statement I Glucose gives a reddish-brown precipitate with Fehling's solution. Statement II Reaction of glucose with Fehling's solution gives CuO\mathrm{CuO} and gluconic acid.

Options

  1. AStatement I is true, Statement II is true, Statement II is a correct explanation for Statement I
  2. BStatement I is true, Statement II is true; Statement II is not a correct explanation for Statement I
  3. CStatement I is true, Statement II is false
  4. DStatement I is false, Statement II is true

Correct answer

C. Statement I is true, Statement II is false

Step-by-step solution

Glucose gives a reddish brown precipitate with Fehling's solution. Solution consists of Cu2+\mathrm{Cu}^{2+} which gets reduced to Cu+(Cu2O)\mathrm{Cu}^{+}\left(\mathrm{Cu}_2 \mathrm{O}\right).
