Question

One mole of P 4 reacts with 8 moles of SOCl 2 to give 4 moles of A , x mole of SO 2 and 2 moles of B . A , B and x respectively are, POCl 3 , S 2 Cl 2 and 2, PCl 3 , S 2 Cl 2 and 4, PCl 3 , S 2 Cl 2 and 2, POCl 3 , S 2 Cl 2 and 4

MARKS App · Accepted Answer

Thionyl chloride reacts with white phosphorus to produce phosphorus trichloride. The other side products in this reaction are sulphur dioxide and Sulphur monochloride. P 4 + 8 SOCl 2 → 4 PCl 3 + 4 SO 2 + 2 S 2 Cl 2 Hence A = PCl 3 , x = 4 , B = S 2 Cl 2
