Step-by-step solution
Suppose that (x ) be the oxidation states of central atoms. A. Oxidation number of ( Cr ⁻ Cr ₂ O ₇²⁻ ) ( aligned 2 x+7(-2) & =-2 2 x-14 & =-2 2 x & =+12 x & =+6 aligned ) B. Oxidation number of ( Mnin MnO ₄⁻ ) ( aligned x+4(-2) & =-1 x-8 & =-1 x & =+7 aligned ) C. Oxidation number of ( V ^ in VO ₃⁻ ) ( aligned x+3(-2) & =-1 x-6 & =-1 x & =+5 aligned ) D. Oxidation number of Fe in ( FeF ₆³⁻ ) ( aligned x+6(-1) & =-3 x-6 & =-3 x & =+3 aligned )
