Answer» Correct Answer - 1 It convert carboxylic acids to acid chlorides `PCl_(3)+3RCO_(2)Hrarr3RCOCl+H_(3)PO_(3)` Catalytic oxidation of phosphorus trichloride gives phosphorus oxychloride: `2PCl_(3)(l)+O_(2)(g)rarr2POCl_(3)(l)` `6PCl_(3)+P_(4)O_(10)+6Cl_(2)rarr10POCl_(3)` It directly combines wiht `Cl_(2),O_(2)` and `S` incdicating that it is an unsatureed compound: `PCl_(3)+Cl_(2)rarrPCl_(5)` `2PCl_(3)+O_(2)rarr2POCl_(3)` `PCl_(3)+SrarrPSCl_(3)` It acts as a reducing agent `PCl_(3)+SO_(2)Cl_(2)rarrPCl_(5)+SO_(2)` `PCl_(3)+SO_(3)rarrPOCl_(3)+SO_(2)` `3PCl_(3)+SOCl_(2)rarrPOCl_(3)+PSCl_(3)+PCl_(5)` |
