Question

Match the following and choose the correct option.

r reduction

• A. a → (i), b → (ii), c → (iii), d → (iv)
• B. a → (iv), b → (iii), c → (ii), d → (i)
• C. a → (iii), b → (ii), c → (iv), d → (i)
• D. a → (i), b → (ii), c → (iv), d → (iii)

Hint:

In organic chemistry, each reagent has specific applications, such as Tollen's reagent for aldehyde detection and Fehling solution for reducing sugars.

Answer 1

The Correct Option is C

Step 1: Analyzing the reactions.
- (a) [Ag(NH$_3$)$_2$]$^+$ is the Tollen's reagent, which is used for the detection of aldehydes.
- (b) Zn-Hg/HCl is used in the Clemmensen reduction, a reduction method for carbonyl compounds.
- (c) NH$_2$-NH/KOH is used in the Wolff-Kishner reduction, which reduces aldehydes and ketones to hydrocarbons.
- (d) Cu$^{2+}$/OH$^-$ forms Fehling solution, used to test for reducing sugars.

Step 2: Conclusion.
Matching the items correctly gives the answer: (3) a → (iii), b → (ii), c → (iv), d → (i).
