Question:
Which of the following tetrahalides does not exist?
Which of the following tetrahalides does not exist?
Show Hint
Pb\textsuperscript{4+} is unstable with I\textsuperscript{–} due to redox instability. PbI\textsubscript{4} decomposes easily.
Updated On: May 18, 2025
- CCl\textsubscript{4}
- SiCl\textsubscript{4}
- PbCl\textsubscript{4}
- PbI\textsubscript{4}
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
PbI\textsubscript{4} does not exist because Pb in +4 oxidation state is unstable in presence of I\textsuperscript{–}, which is a good reducing agent. Pb\textsuperscript{4+} gets reduced to Pb\textsuperscript{2+} and iodine gets oxidized.
