Question:
The species formed on fluorination of phosphorus pentachloride in a polar organic solvent are:
The species formed on fluorination of phosphorus pentachloride in a polar organic solvent are:
Show Hint
Ionization in polar organic solvents often results in stable ionic species depending on the halogen substitution.

- \([PF_4]^+ [PF_6]^-\) and \([PCl_4]^+ [PF_6]^-\)
- \([PCl_4]^+ [PCl_4F_2]^-\) and \([PCl_4]^+ [PF_6]^-\)
- \(PF_3\) and \(PCl_3\)
- \(PF_5\) and \(PCl_3\)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
When \(PCl_5\) is fluorinated in a polar organic solvent, it undergoes ionization to form:
\[
[PCl_4]^+ \text{ and } [PCl_4F_2]^-.
\]
On further fluorination:
\[
[PCl_4]^+ \text{ and } [PF_6]^- \text{ are also formed}.
\]
Thus, the correct answer is (B).
