Match the LIST-I with LIST-II \( array |c|l|c|l| & List-I (Reagents) & & List-II (Name of reaction \\ & & & involving carbonyl compounds) \\ A. & NH_2 - NH_2,\ KOH & I. & Tollen's Test \\ B. & Ag(NH_3)_2OH & II. & Clemmensen Reduction \\ C. & array l Aq. CuSO_4 , \\ Sodium potassium \\ tartarate, KOH array & III. & Wolff--Kishner Reduction \\ D. & Zn - Hg,\ HCl & IV. & Fehling's Test \\ array \) Choose the correct answer from the options given below:
C. A-III, B-I, C-IV, D-II
The matching of reagents with their respective named reactions is as follows: A. NH_2-NH_2, KOH (Hydrazine in basic medium) is the reagent for Wolff-Kishner Reduction, which reduces carbonyl groups to alkanes. So, A matches with III. B. [Ag(NH_3)_2]OH (Ammoniacal silver nitrate) is Tollen's reagent used for Tollen's Test to identify aldehydes. So, B matches with I. C. Aqueous CuSO_4 (Fehling's A) and Sodium potassium tartarate in KOH (Fehling's B) are the components of Fehling's solution used for Fehling's Test. So, C matches with IV. D. Zn-Hg, HCl (Zinc amalgam in concentrated hydrochloric acid) is the reagent for Clemmensen Reduction, which reduces carbonyl groups to alkanes. So, D matches with II. The correct matching is A-III, B-I, C-IV, D-II.
