Q. In which of the following compounds, the oxidation number of iodine is fractional?
A) ${IF}_{3}$
B) ${IF}_{5}$
C) $I_{3}^{-}$
D) ${IF}_{7}$
Explanation
(c)
Oxidation number of iodine in given species is as follows
O.N. of iodine in ${IF}_{3}$=+3
O.N. of iodine in $I_{3}^{-} = - \frac{1}{3}$
O.N. of iodine in ${IF}_{5}$=+5
O.N. of iodine in ${IF}_{7} = + 7$
