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) P₂O₃ + 3H₂O →; (Q) P₄ + 3NaOH + 3H₂O →; (R) PCl₅ + CH₃COOH →; (S) H₃PO₂ + 2H₂O + 4AgNO₃ →. List-II: (1) P(O)(OCH₃)Cl₂; (2) H₃PO₃; (3) PH₃; (4) POCl₃; (5) H₃PO₄.
