Step-by-step solution
In C ₃ O ₂ (carbon suboxide, O = C = C = C = O ), the terminal carbon atoms have an oxidation state of +2 and the central carbon atom has an oxidation state of 0 . In Br ₃ O ₈ (tribromooctaoxide, O ₃ Br - BrO ₂- BrO ₃ ), the terminal bromine atoms have an oxidation state of +6 and the central bromine atom has an oxidation state of +4 . In Na ₂ S ₄ O ₆ (sodium tetrathionate, Na ^+ O ^- SO ₂- S - S - SO ₂ O ^- Na ^+ ), the terminal sulphur atoms have an oxidation state of +5 and the central sulphur atoms have an oxid
