Phosphorus trichloride can be obtained from white phosphorus by the action ofA. `Cl_(2)`B. `SOCl_(2)`C. `SO_(2)Cl_(2)`D. Both (1) and (2) |
|
Answer» Correct Answer - 4 Phosphrous trichloride (a colourless liquid)is produced when chlorine gas reacts with an excess of white phosphorus: `P_(4)(s)+6Cl_(2)(g)rarr4PCl_(3)(l)` An excess of chloride results in phosphrous pentachloride (a white solid), `P_(4)(s)+10Cl_(2)(g)rarr4PCl_(5)(g)` Action of thionyl chloride on white phosphorus yields phosphorus trichloride while action of sulphuryl chloride on white to phosphorus yields phosphorus pentachloride: `P_(4)+8SOCl_(2)rarr4PCl_(3)+4SO_(2)+2S_(2)Cl_(2)` `P_(4)+10SO_(2)Cl_(2)rarr4PCl_(5)+10SO_(2)` |
