The correct statement for the molecule, `CsI_(3)`, is-

Options

A. it contains `Cs^(+),I^(-)` and lattice `I_(2)` molecule
B. it is a covalent molecule
C. it contains `Cs^(+)` and `I_(3)^(-)` ions.
D. it contains `Cs^(3+) and I^(-)` ions.

Answer

C

Explanation

Cs cannot show +3 oxidation state. So, `CsI_(3)` is formulated as `Cs^(+) and I_(3)^(-)` ions. It is a typical ionic compound.
