The correct statement for the molecule $$ CsI_{3}$$ is that:

Ait contains $$ Cs^{3+}$$ and $$ I^{-}$$ ions
Bit contains $$ Cs^{+}, I^{-}$$ and lattice $$ I_{2}$$ molecule
Cit is a covalent molecule
Dit contains $$ Cs^{+}$$ and $$ I_{3}{^-}$$ ions
Correct Answer

Solution

$$ CsI_{3} \rightarrow Cs^{+}+{I_3}^{-}$$

$$ \Rightarrow Cs$$ cannot show $$+3$$ oxidation state.

$$ \Rightarrow I_{2}$$ molecules are too large to be accommodated in the lattice.

Hence, the correct option is $$D$$
