Correct answer
CA-III, B-I, C-IV, D-II
Step-by-step explanation
The matching of reagents with their respective named reactions is as follows:
A. (Hydrazine in basic medium) is the reagent for Wolff-Kishner Reduction, which reduces carbonyl groups to alkanes. So, A matches with III.
B. (Ammoniacal silver nitrate) is Tollen's reagent used for Tollen's Test to identify aldehydes. So, B matches with I.
C. Aqueous (Fehling's A) and Sodium potassium tartarate in (Fehling's B) are the components of Fehling's solution used for Fehling's Test. So, C matches with IV.
D. (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.
