The correct statement for the molecule CsI 3 , is :
Options
- AIt is a covalent molecule.
- BIt contains Cs + and I 3 - ions.
- CIt contains Cs 3 + and I - ions.
- DIt contains Cs + , I - and lattice I 2 molecule.
Correct answer
B. It contains Cs + and I 3 - ions.
Step-by-step solution
I 3 - ion is made by the addition of excess iodine to iodide solution. I 2 + I - → I 3 - Cs will always be in +1 oxidation state.
