Q11 / 66 · JEE Advanced 2007 (Paper 2) · Chemistry

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

  • A
    Statement I is true, Statement II is true, Statement II is a correct explanation for Statement I
  • B
    Statement I is true, Statement II is true; Statement II is not a correct explanation for Statement I
  • Correct answer
    C
    Statement I is true, Statement II is false
  • D
    Statement I is false, Statement II is true

Solution

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

Hence, the correct answer is option: 'C'.
