In Chromyl chloride, the oxidation state of chromium is + ___________.

Correct answer

Step-by-step solution

The chemical formula of Chromyl chloride is CrO 2 Cl 2 . The oxidation state of chromium in chromyl chloride ( CrO 2 Cl 2 ) is + 6 . Let the oxidation number of Chromium be “ x ”, the oxidation state of oxygen is - 2 , the oxidation state of chlorine is - 1 . Then, x   +   2 ( - 2 )   +   2 ( - 1 )   =   0 x - 6 = 0 x = 6
