Determine the product formed when phosphine gas is mixed with chlorine gas
Options
- AThe mixture only cools down
- BPH 3 ⋅ Cl 2 adduct is formed with warming up
- CP C l 5 and H C l are formed and the mixture cools down
- 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.
