Chemistry Question on Stoichiometry and Stoichiometric Calculations
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) | P2O3 + 3H2O →| (1) | P(O)(OCH3)Cl2
(Q) | P4 + 3NaOH + 3H2O →| (2) | H3PO3
(R) | PCl5 + CH3COOH → | (3)| PH3
(S) | H3PO2 + 2H2O + 4AgNO3 →| (4) | POCl3
| | (5) | H3PO4
A
P →2; Q→ 3; R →1; S →5
B
P →3; Q→ 5; R →4; S →2
C
P →5; Q→ 2; R →1; S →3
D
P →2; Q→ 3; R →4; S →5
Answer
P →2; Q→ 3; R →4; S →5
Explanation
Solution
Correct option is (D) P → 2; Q → 3; R → 4; S → 5
P3PO2+H20+AGNO3→H3PO4+HNO3+Ag↓
P is equivalent to 2, Q is equivalent to 3, R is equivalent to 4, and S is equivalent to 5.
