The oxidation state of chromium in Cr(CO)₆ is:

A.+2

B.+4

C.+6✓ Correct

D.+7

Explanation

Let us consider the oxidation number of S is x. Now by adding all the charges and equating it to zero, we get- 2 4 H SO 2+x-8=0 x=+6 → >> 16. Oxidation state of oxygen in F₂O is (a) +1 (b) -1 (c) +2 (d) -2 Here, central atom is oxygen and F is more electronegative. Let us consider the oxidation states for Oxygen in given compound, →-2 + x =0,x=+2
