Question

Valency of iron in $FeC{l}_2$ and $FeC{l}_3$ is _______ and _______ respectively.

• A. 1, 2
• B. 2, 4
• C. 2, 3
• D. 3, 2

Answer 1

The correct option is C

2, 3

Let the valency of Sn =x,

For $FeC{l}_2$ :

Since valency of Cl is -1.

x +(-1 × 2) = 0,

So, x = 2,

For $FeC{l}_3$:

x +(-1 × 3) = 0,

So, x = 3
