$TlI_3 \Rightarrow Tl^{3+}, 3I^{-}$

Vedclass · Answer

(B) The incorrect match is $TlI_3 \Rightarrow Tl^{3+}, 3I^{-}$.Due to the inert pair effect, $Tl^{3+}$ is highly unstable and acts as a strong oxidizing agent, while $I^-$ is a strong reducing agent. Therefore, $Tl^{3+}$ oxidizes $I^-$ to $I_2$, and itself gets reduced to $Tl^+$. The $I_2$ molecules combine with $I^-$ to form the triiodide ion $(I_3^-)$.Thus, $TlI_3$ actually exists as $Tl^+$ and $I_3^-$ ions $(TlI_3 \Rightarrow Tl^{+}, I_3^{-})$.The other matches correctly represent the typical ionic dissociation of the respective compounds.
