Among the following, the number of compounds that can react with PCl_(5) to give POCl_(3)" is ":O_(2),CO_(2),SO_(2),H_(2)O,H_(2)SO_(4),P_(4)O_(10).

Answer»


Solution :these are :
(i) `2PCl_(5)+O_(2)overset(DELTA)to2POCl_(3)+2Cl_(2),`
(II) `[PCl_(5)toPCl_(3)+Cl_(2), 2PCl_(2)+O_(2)to2POCl_(3)]`
(iii) `PCl_(5)+SO_(2)toPOCl_(3)+SOCl_(2)`
(iv) `PCl_(5)+H_(2)OtoPOCl_(3)+2HCl,`
`POCl_(3)` further reacts with `H_(2)O` to give `H_(3)PO_(4)`
`POCl_(3)+3H_(2)OtoH_(3)PO_(4)+3HCl`
(V) `2PCl_(5)+H_(2)SO_(4)to2POCl_(3)+SO_(2)Cl_(2)+2HCl`
(vi) `6PCl_(5)+P_(4)O_(10)to10POCl_(3)`
