Question

Match the following:

List-I (Name of Reagent)		List-II (Composition)
A	Jones reagent	I	\(\mathrm{Zn\!-\!Hg/HCl}\)
B	Clemmensen reagent	II	Conc. HCl + anhyd. \(\mathrm{ZnCl_2}\)
C	Tollens' reagent	III	\(\mathrm{CrO_3/H_2SO_4}\)
D	Lucas reagent	IV	\([\mathrm{Ag(NH_3)_2}]^{+}\)
		V	\(\mathrm{SnCl_2/HCl}\)

The correct answer is

• A. A--III, B--IV, C--V, D--II
• B. A--III, B--I, C--IV, D--II
• C. A--II, B--I, C--IV, D--III
• D. A--V, B--III, C--II, D--I

Hint:

Important reagents: \[ \boxed{ \begin{aligned} &\text{Jones reagent} &&\rightarrow \mathrm{CrO_3/H_2SO_4}, &\text{Clemmensen reagent} &&\rightarrow \mathrm{Zn(Hg)/HCl}, &\text{Tollens' reagent} &&\rightarrow [\mathrm{Ag(NH_3)_2}]^{+}, &\text{Lucas reagent} &&\rightarrow \text{Conc. HCl + anhyd. ZnCl}_2. \end{aligned} } \]
