Verified By Collegedunia
The Correct Option is B
Solution and Explanation
PCl5 Fluorination Reaction
When \( \text{PCl}_5 \) is fluorinated in a polar organic solvent, it ionizes to form:
\[ [\text{PCl}_4]^+ \quad \text{and} \quad [\text{PCl}_4 \text{F}_2]^- \]
Upon further fluorination:
\[ [\text{PCl}_4]^+ \quad \text{and} \quad [\text{PF}_6]^- \]
Final Answer:
The correct option is (B).
