Question

The pair of compounds that can exist together is (A)  textFeC textl3 , Kl (B)  textFeC textl3, textSnC textl2 (C)  textFeC textl2, textSnC textl2 (D)  textHgC textl2, textSnC textl2

As textFeC textl2, textSnC textl2 both are reducing agents, so reaction is not possible between them. Hence, they can exist together. In rest of other pairs redox reaction occurs so they cannot exist together.

Q. The pair of compounds that can exist together is

$FeC l_{3}$ , $K l$

$FeC l_{3}, SnC l_{2}$

$FeC l_{2}, SnC l_{2}$

$HgC l_{2}, SnC l_{2}$

As $FeC l_{2}, SnC l_{2}$ both are reducing agents, so reaction is not possible between them. Hence, they can exist together.
