Question 46

In the compound [ICl2]+[FeCl4]−[\text{ICl}_2]^+ [\text{FeCl}_4]^-[ICl2​]+[FeCl4​]−, the oxidation number of chlorine is -1.

What are the oxidation numbers of I\text{I}I and Fe\text{Fe}Fe in the compound?

A

I=+1\text{I} = +1I=+1, Fe=+3\text{Fe} = +3Fe=+3

B

I=+3\text{I} = +3I=+3, Fe=+2\text{Fe} = +2Fe=+2

C

I=+3\text{I} = +3I=+3, Fe=+3\text{Fe} = +3Fe=+3

D

I=+1\text{I} = +1I=+1, Fe=+2\text{Fe} = +2Fe=+2
