Iodine pentoxide easily oxidises carbon monoxide to carbon dioxide at room temperature: 5 CO + I 2 O 5 → I 2 + 5 CO 2. This reaction can be used to analyze the concentration of CO in a gaseous sample. I 2 O 5 forms iodyl salts, [IO 2 +], with SO 3 and S 2 O 6 F 2, but iodosyl salts, [IO +], with concentrated sulfuric acid.
Iodine pentoxide (I 2 O 5) Iodine oxides are chemical compounds of oxygen and iodine. Iodine has only two stable oxides which are isolatable in bulk, iodine tetroxide and iodine pentoxide, but a number of other oxides are formed in trace quantities or have been hypothesized to exist. The chemistry of these compounds is complicated with only a ...
Structure of iodine pentoxide. Iodine oxides are the most stable of all the halogen oxides, because of the strong I–O bonds resulting from the large electronegativity difference between iodine and oxygen, and they have been known for the longest time. [11] The stable, white, hygroscopic iodine pentoxide (I 2 O 5) has

In iodane chemistry, carbon is considered more electronegative than iodine, despite the Pauling electronegativities of those respective atoms. [2] Thus iodobenzene (C 6 H 5 I) is an iodine(I) compound, (dichloroiodo)benzene (C 6 H 5 ICl 2) and iodosobenzene (C 6 H 5 IO) iodine(III) compounds, and iodoxybenzene (C 6 H 5 IO 2) an iodine(V) compound.
When heated above 150 °C, decomposition into diiodine pentoxide can be observed: 2 I 2 O 6 → 2 I 2 O 5 + O 2. The compound is diamagnetic, which is attributed to the different oxidation numbers of the iodine atoms. [2] Structurally, the compound is iodyl periodate, an iodine(V,VII) oxide approximating IO 2 + IO 4 −. [2]
This periodic order also follows the atomic radius of halogens and the length of the carbon-halogen bond. For example, in the molecules represented by CH 3 X, where X is a halide, the carbon-X bonds have strengths, or bond dissociation energies, of 115, 83.7, 72.1, and 57.6 kcal/mol for X = fluoride, chloride, bromide, and iodide, respectively.

The structure consists of pyramidal molecules linked by hydrogen bonding and intermolecular iodine-oxygen interactions. The I=O bond lengths are 1.81 Å while the I–OH distance is 1.89 Å.
