Determine the product formed when phosphine gas is mixed with chlorine gas

Options

  1. AThe mixture only cools down
  2. BPH 3 ⋅ Cl 2 adduct is formed with warming up
  3. CP C l 5 and H C l are formed and the mixture cools down
  4. DP C l 3 and H C l are formed and the mixture warms up

Correct answer

C. P C l 5 and H C l are formed and the mixture cools down

Step-by-step solution

The reaction of phosphine gas with chlorine gas is given as, P H 3 + 4 C l 2 → P C l 5 + 3 H C l Therefore, the products formed when phosphine gas is mixed with chlorine gas are PCl 5 and HCl . The mixture will cool down later.
