What is the Lewis structure of IO 4-ion?
When we form these three double bonds with the Oxygens here, we can see that the Iodine now has a formal charge of 0, and these Oxygens with the double bonds, they also have a formal charge of 0. And the single bond stayed the same. We didn't change that. That has a formal charge of negative 1. That negative 1 matches the -1 charge on the IO4- ion.

How many valence electrons are in io4?
For, IO4- there are 32 valence electrons pairs, so total pairs of electrons are 16.

How many valence electrons does iodine hold?
Iodine is in Period 5 on the Periodic table. Therefore it can hold more than 8 valence electrons. You'll want to check the formal charges to make sure that you have the best structure for IO 4-. This means the structure with the formal charges closest to zero as possible.
Which element is the least electronegative?
Iodine is the least electronegative, we'll put that at the center, and the Oxygens will go around the outside. We'll put 2 electrons between the atoms to form the chemical bonds. Then we'll go around the outside to fill the octets on the Oxygens until we use all 32 valence electrons. So we have 8, 10, 12, and 32.

How many electrons does iodine have?
Also there is a -1 overall charge on the IO 4- ion. Iodine and oxygen are located at 7 and 6 groups respectively in the periodic table. So iodine has seven electrons in its valence shell and for oxygen atom, there are six electrons in its valence shell.
How many lone pairs does an oxygen atom have?
Next step is, marking those twelve valence electrons pairs on outside atoms (in this case, oxygen atoms) as lone pairs. One oxygen atom will take three lone pairs following the octal rule (oxygen atoms cannot keep more than eight electrons in their valence shells).
Why is it important to mark charges of atoms?
If charges exist on atoms, they should be marked on now. Marking charges of atoms is important because it is used to determine the best lewis structure. Each oxygen atom has a -1 charge and iodine has a +3 charge. Having so many charges on atoms on a structure is not good to be the lewis structure.
Why is the above drawn structure not stable?
Above drawn structure is not a stable one because there are charges on every atoms. Therfore, we should try to convert lone pairs to bonds to reduce charges on atoms (if possible).
Can we reduce charges in Lewis structure?
But, if possible, we can try to reduce charges furthermore to obtain the best lewis structure. yes,we can reduce one more electron pair (lone pair) of another oxygen atom (which holds a negative charge) to a I-O bond. Now, there are fourteen electrons around iodine atom.
What is the oxidation state of iodine?
Periodate is part of a series of oxyanions in which iodine can assume oxidation states of −1, +1, +3, +5, or +7. A number of neutral iodine oxides are also known.
What type of bonds can periodates cleave?
Cleavage reactions. Periodates can cleave carbon–carbon bonds on a variety of 1,2-difunctionalised alkanes. The most common example of this is diol cleavage, which was also the first to be discovered ( Malaprade reaction ). In addition to diols, periodates can cleave 1,2-hydroxy ketones, 1,2-diketones, α-keto acids, α-hydroxy acids, amino acids, ...
Why is periodate cleavage important?
Periodate cleavage is often utilized in molecular biochemistry for the purposes of modifying saccharide rings, as many five- and six-membered sugars have vicinal diols. Historically it was also used to determine the structure of monosaccharides.
What can periodates cleave?
In addition to diols, periodates can cleave 1,2-hydroxy ketones, 1,2-diketones, α-keto acids, α-hydroxy acids, amino acids, 1,2-amino alcohols, 1,2-diamines, and epoxides to give aldehydes, ketones, and carboxylic acids. Alkenes can also be oxidised and cleaved in the Lemieux–Johnson oxidation.
What is a periodate?
Chemical compound. Periodate / pəˈraɪ.ədeɪt / is an anion composed of iodine and oxygen. It is one of a number of oxyanions of iodine and is the highest in the series, with iodine existing in oxidation state +7. Unlike other perhalogenates, such as perchlorate, it can exist in two forms: metaperiodate IO−.
Is iodine a hypervalent compound?
In both the ortho- and metaperiodate the iodine is hypervalent, as it forms more bonds than would classically be allowed. This has been explained in terms of dative bonds, confirming the absence of double bonding in these molecules.
Can alkenes be oxidized?
Alkenes can also be oxidised and cleaved in the Lemieux–Johnson oxidation. This uses a catalytic loading of osmium tetroxide which is regenerated in situ by the periodate. The overall process is equivalent to that of ozonolysis . Cleavage reactions proceed via a cyclic intermediate called a periodate ester.
