In which of the following halogen oxides do the halogen atoms exhibit both +6 and +4 oxidation states within the same molecule?

Step-by-step solution

Let us evaluate the individual oxidation states of the halogen atoms in the given molecules: 1) In Cl ₂ O ₇ , the oxidation state of chlorine is +7 . 2) In Cl ₂ O ₆ , the average oxidation state is +6 , but structurally it exists as [ ClO ₂]^+[ ClO ₄]^- in the solid state, exhibiting +5 and +7 oxidation states. 3) In I ₂ O ₅ , the oxidation state of iodine is +5 . 4) In Br ₃ O ₈ (tribromooctaoxide), the structure consists of a linear chain of three bromine atoms. The two terminal bromine atoms are each bonded to th
