Among the following, the number of compounds than can react with PC l 5 to give POC l 3 are O 2 , C O 2 , S O 2 , H 2 O , H 2 S O 4 , P 4 O 10

Correct answer

4

Step-by-step solution

PC l 5 on reaction with these 4 compounds gives POC l 3 PC l 5 + S O 2 → POC l 3 + SOC l 2 PC l 5 + H 2 O → POC l 3 + 2HCl PC l 5 + H 2 S O 4 → S O 2 C l 2 + 2POC l 3 + 2HCl 6PC l 5 + P 4 O 10 → 10 POC l 3
