Identify the principal phosphorous containing products X . Y and Z for each of the follow in reactions and give answer of the given questions.
(i) deficiency of oxygen
(ii) excess of dry
(iii) Reduction of phosphate rock by red hot carbon in the presence of sand → (Z) (white waxy solid)
Finely divided Sn on heating with Y produces -
Options:
Answer:
B
Solution:
Identify Y: In reaction (ii), white phosphorus (P₄) reacts with an excess of dry chlorine (Cl₂) in an inert atmosphere of CO₂ to form phosphorus pentachloride, so Y = PCl₅.
Reaction with Sn: When finely divided tin (Sn) is heated with PCl₅, it undergoes an oxidation-reduction reaction where tin acts as a reducing agent.
Products formed: The reaction yields tin(IV) chloride and phosphorus trichloride:
