Question 58

In Chromyl chloride, the oxidation state of chromium is $$(+)$$ _____.

Correct Answer: 6

Solution

Chromyl chloride has the formula CrO₂Cl₂.

Let the oxidation state of Cr be $$x$$:

$$x + 2(-2) + 2(-1) = 0$$

$$x - 4 - 2 = 0$$

$$x = +6$$

The oxidation state of chromium is $$\mathbf{+6}$$.
