Which of the following reaction proves the chlorinating property of phosphorus pentachloride?

Options

  1. A( PCl ₅+ H ₂ O POCl ₃+2 HCl )
  2. B(2 PCl ₅+ Sn SnCl ₄+2 PCl ₃ )
  3. C( PCl ₅ PCl ₃+ Cl ₂ )
  4. D( P ₄+10 Cl ₂ 4 PCl ₅ )

Correct answer

D. ( P ₄+10 Cl ₂ 4 PCl ₅ )

Step-by-step solution

PCl ₅ PCl ₃+ Cl ₂ The trigonal bipyramidal structure of phosphorus pentachloride, in which the P - Cl (axial) bonds are somewhat larger than the P - Cl (equatorial) bonds, renders the molecule particularly unstable. It serves as a chlorinating agent when it dissociates, releasing two chlorine atoms from the axial bond. PCl ₅ PCl ₃+ Cl ₂ act as chlorinating agent
