Write a lewis structure clo2f

The Lewis structure for ClO2- is requires you to place Chlorine Cl in the center of the structure since it is the most electronegative.

Lewis dot structures provide a simple model for rationalizing the bonding in most known compounds. However, there are three general exceptions to the octet rule: Odd Number of Electrons Because most molecules or ions that consist of s- and p-block elements contain even numbers of electrons, their bonding can be described using a model that assigns every electron to either a bonding pair or a lone pair.

Molecules or ions containing d-block elements frequently contain an odd number of electrons, and their bonding cannot adequately be described using the simple approach we have developed so far. Bonding in these compounds will be discussed in Chapter 23 "The ". There are, however, a few molecules containing only p-block elements that have an odd number of electrons.

Some important examples are nitric oxide NOwhose biochemical importance was described in earlier chapters; nitrogen dioxide NO2an oxidizing agent in rocket propulsion; and chlorine dioxide ClO2which is used write a lewis structure clo2f water purification plants.

Consider NO, for example. More Than an Octet of Electrons The most common exception to the octet rule is a molecule or an ion with at least one atom that possesses more than an octet of electrons.

Such compounds are found for elements of period 3 and beyond. If we arrange the atoms and electrons symmetrically, we obtain a structure with six bonds to sulfur; that is, it is six-coordinate.

Each fluorine atom has an octet, but the sulfur atom has 12 electrons surrounding it rather than 8. The third step in our procedure for writing Lewis electron structures, in which we place an electron pair between each pair of bonded atoms, requires that an atom have more than 8 electrons whenever it is bonded to more than 4 other atoms.

The octet rule is based on the fact that each valence orbital typically, one ns and three np orbitals can accommodate only two electrons. To accommodate more than eight electrons, sulfur must be using not only the ns and np valence orbitals but additional orbitals as well.

Sulfur has an [Ne]3s23p43d0 electron configuration, so in principle it could accommodate more than eight valence electrons by using one or more d orbitals. Thus species such as SF6 are often called expanded-valence molecules A compound with more than an octet of electrons around an atom.

Whether or not such compounds really do use d orbitals in bonding is controversial, but this model explains why compounds exist with more than an octet of electrons around an atom. There is no correlation between the stability of a molecule or an ion and whether or not it has an expanded valence shell.

Some species with expanded valences, such as PF5, are highly reactive, whereas others, such as SF6, are very unreactive. In fact, SF6 is so inert that it has many commercial applications.

If we use a single pair of electrons to connect the sulfur and each oxygen, we obtain the four-coordinate Lewis structure a. We know that sulfur can accommodate more than eight electrons by using its empty valence d orbitals, just as in SF6.

Lewis structure and chemical reaction

We can draw five other resonance structures equivalent to b that vary only in the arrangement of the single and double bonds. Note the Pattern In oxoanions of the heavier p-block elements, the central atom often has an expanded valence shell.

Less Than an Octet of Electrons Molecules with atoms that possess less than an octet of electrons generally contain the lighter s- and p-block elements, especially beryllium, typically with just four electrons around the central atom, and boron, typically with six.

One example, boron trichloride BCl3 is used to produce fibers for reinforcing high-tech tennis rackets and golf clubs. The compound has 24 valence electrons and the following Lewis structure: The boron atom has only six valence electrons, while each chlorine atom has eight.

A reasonable solution might be to use a lone pair from one of the chlorine atoms to form a B-to-Cl double bond: The high electronegativity of Cl makes this separation of charge unlikely and suggests that this is not the most important resonance structure for BCl3.

This conclusion is shown to be valid based on the three equivalent B—Cl bond lengths of pm that have no double bond character.

Electron-deficient compounds such as BCl3 have a strong tendency to gain an additional pair of electrons by reacting with species with a lone pair of electrons. Note the Pattern Molecules with atoms that have fewer than an octet of electrons generally contain the lighter s- and p-block elements.

Note the Pattern Electron-deficient compounds have a strong tendency to gain electrons in their reactions.

Example 8 Draw Lewis dot structures for each compound. BeCl2 gas, a compound used to produce beryllium, which in turn is used to produce structural materials for missiles and communication satellites SF4, a compound that reacts violently with water Include resonance structures where appropriate.

Lewis electron structures Strategy: A Use the procedure given earlier to write a Lewis electron structure for each compound.Write a Lewis structure for each of the following ions. Assign formal charges to all atoms. If necessary, expand the octet on the central atom to lower formal charge%(15).

The ClO2 Lewis structure has 19 valence electrons meaning that there will be an odd number of valence electrons in the structure. For the Lewis structure for ClO2 you should take formal charges into account to find the best Lewis structure for the molecule. For the ClO2 Lewis structure, calculate the total number of valence electrons for the ClO2 molecule.

A Lewis structure is a graphic representation of the electron distribution around atoms. The reason for learning to draw Lewis structures is to predict the number and type of . The Lewis structure of a covalent compound or polyatomic ion shows how the valence electrons are arranged among the atoms in the molecule to show the connectivity of the atoms.
