JEE Chemistry Practice Question

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

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