What is the action of concentrated sulphuric acid on phosphorous pentachloride
Advertisements
उत्तर
Concentrated sulphuric acid reacts with PCl5 to form chlorosulphuric acid.
`HOSO_2OH + PCl_5 -> ClSO_2OH + POCl_3 +HCl`
Sulphuric acid Phosphorus Chlorosulphuric acid
pentachloride
Chlorosulphuric acid further reacts with PCl5 to form sulphuryl chloride.
`ClSO_2OH + PCl_5 -> ClSO_2Cl + POCl_3 + HCL`
Chlorosulphuric Phosphorus Sulphuryl
acid pentachloride chloride
