JEE Advanced 2023 — Paper 1 — Question 43

Match the reactions (in the given stoichiometry of the reactants) in List-I with one of their products given in List-II

and choose the correct option.

LIST-I	LIST-II
P) $\mathrm{P}_{2} \mathrm{O}_{3}+3 \mathrm{H}_{2} \mathrm{O} \rightarrow$	$(1) \mathrm{P}(\mathrm{O})\left(\mathrm{OCH}_{3}\right) \mathrm{Cl}_{2}$
Q) $\mathrm{P}_{4}+3 \mathrm{NaOH}+3 \mathrm{H}_{2} \mathrm{O} \rightarrow$	$(2) \mathrm{H}_{3} \mathrm{PO}_{3}$
R) $(\mathrm{R}) \mathrm{PCl}_{5}+\mathrm{CH}_{3} \mathrm{COOH} \rightarrow$	$(3) \mathrm{PH}_{3}$
S) $(\mathrm{~S}) \mathrm{H}_{3} \mathrm{PO}_{2}+2 \mathrm{H}_{2} \mathrm{O}+4 \mathrm{AgNO}_{3} \rightarrow$	$(4) \mathrm{POCl}_{3}$
	$(5) \mathrm{H}_{3} \mathrm{PO}_{4}$

Option A:
$\mathrm{P} \rightarrow 2 ; \mathrm{Q} \rightarrow 3 ; \mathrm{R} \rightarrow 1$ ; $\mathrm{S} \rightarrow 5$
Option B:
$\mathrm{P} \rightarrow 3$ ; Q $\rightarrow 5$ ; R $\rightarrow 4$ ; $\mathrm{S} \rightarrow 2$
Option C:
$\mathrm{P} \rightarrow 5$ ; Q $\rightarrow 2 ; \mathrm{R} \rightarrow 1$ ; $\mathrm{S} \rightarrow 3$
Option D:
$\mathrm{P} \rightarrow 2 ; \mathrm{Q} \rightarrow 3 ; \mathrm{R} \rightarrow 4$ ; $\mathrm{S} \rightarrow 5$
Correct

Answer: D

Step-by-step solution

$\mathrm{P}_{2} \mathrm{O}_{3}+3 \mathrm{H}_{2} \mathrm{O} \longrightarrow 2 \mathrm{H}_{3} \mathrm{PO}_{3}$ $\mathrm{P}_{4}+3 \mathrm{NaOH}+3 \mathrm{H}_{2} \mathrm{O} \longrightarrow \mathrm{PH}_{3}+3 \mathrm{NaH}_{2} \mathrm{PO}_{2}$ $\mathrm{PCl}_{5}+\mathrm{CH}_{3} \mathrm{COOH} \longrightarrow \mathrm{CH}_{3} \mathrm{COCl}+\mathrm{POCl}_{3}+\mathrm{HCl}$ $\mathrm{H}_{3} \mathrm{PO}_{2}+2 \mathrm{H}_{2} \mathrm{O}+4 \mathrm{AgNO}_{3} \longrightarrow \mathrm{H}_{3} \mathrm{PO}_{4}+4 \mathrm{Ag}+4 \mathrm{HNO}_{3}$ $\mathrm{P} \rightarrow 2, \mathrm{Q} \rightarrow 3, \mathrm{R} \rightarrow 4, \mathrm{~S} \rightarrow 5$
