Question

Valency of tin in $SnC{l}_2$ and $SnC{l}_4$ is _______ and _______ respectively.

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

Answer 1

The correct option is A

2, 4

Let the valency of Sn =x,

For $SnC{l}_2$ :

Since valency of Cl is -1.

x +(-1 × 2) = 0,

So, x = 2,

For $SnC{l}_4$:

x +(-1 × 4) = 0,

So, x = 4
