The pair of compounds that can exist together is:

Options

A. `FeCl_(3)`, `SnCl_(2)`
B. `HgCl_(2)`, `SnCl_(2)`
C. `FeCl_(2)`, `SnCl_(2)`
D. `FeCl_(3)`, `KI`

Answer

C

Explanation

The compounds with lower oxidation number and which cannot reduced by one another can exist together. Thus `FeCl_(2)` and `SnCl_(2)` can exist together as `Fe^(2+)` cannot be reduced by `Sn^(2+)`.
