Ozone hybrid orbitals

Ozone, which has 18 valehce electrohs, exemplifies bent molecules. Another example is the hitrite ahioh, the subject of Extra Practice Exercise. The bohdihg of NO2 can be represented using s p hybrid orbitals for the inner nitrogen atom and one set of delocalized n orbitals. 

Write Lewis formulas for molecular oxygen and ozone. Assuming that all of the valence electrons in the oxygen atoms are in hybrid orbitals, what would be the hybridization of the oxygen atoms in each substance Prepare sketches of the molecules. 

To account for other molecular shapes within a given electron-group arrangement, we postulate that one or more of the hybrid orbitals contains lone pairs. In ozone (O3), for example, the central O is sp hybridized and a lone pair fills one of its three sp orbitals, so ozone has a bent molecular shape. 

The structure of ozone can also be explained in terms of sp hybridization of the atomic orbitals of the oxygen atoms. Sigma (a) bonds are formed by overlap of the hybrid orbitals. 

Take ozone, for instance. Valence bond theory says that ozone is a resonance hybrid of two equivalent structures, both of which have two 0-0 <7 bonds and one 0=0 it bond (Section 7.7). One structure has a lone pair of electrons in the p orbital on the left-hand oxygen atom and a ir bond to the right-hand oxygen. The other structure has a lone pair of electrons in the p orbital on the right-hand... 

In ozone, O3, the two oxygen atoms on the ends of the molecule are equh ent to one another, (a) What is the best choice of hybridization scheme for the atoms of ozone (b) For one of the resonance forms of ozone, which of the orbitals are used to make bonds and which are used to hold nonbonding pairs of electrons (c) Which of the orbitals can be used to delocalize the TT electrons (d) How many electrons are delocalized in the TT system of ozone ... 

A molecule of ozone (O3) consists of three oxygen atoms covalently bonded together in a V-shaped molecule. As such it provides an appropriate example for discussing different aspects of the various approaches to covalent bonding resonance forms and bond order, formal charge and bond polarization, and the hybridization of molecular orbitals. Ozone is also of note in terms of its environmental significance both in the lower levels of the stratosphere and at ground level .
