2. write the resonance forms of ozone, o₃, the component of the upper atmosphere that protects the earth from ultraviolet radiation. what is the order of the bonds in o₃?

Answer

Brief Explanations:

Resonance forms are alternative Lewis structures for a molecule. For ozone ((O_3)), we start by calculating the total number of valence electrons. Each (O) atom has 6 valence electrons, so for (O_3), the total number of valence electrons is (3\times6 = 18). The central (O) atom forms bonds with two other (O) atoms. In one resonance form, the central (O) has a double bond with one (O) and a single bond with the other. The oxygen - oxygen bond order is calculated using the formula ( \text{Bond order}=\frac{\text{Number of bonding electron pairs}}{\text{Number of bonds}}). In (O_3), the number of bonding electron pairs is 3 (since there are 3 pairs of electrons involved in bonding between the three (O) atoms in the resonance hybrid) and the number of (O - O) bonds is 2.

Answer:

The two resonance forms of (O_3) are: (\ce{O - O = O}) and (\ce{O = O - O}) (where the double - bond can be on either side of the central (O) atom). The bond order of the (O - O) bonds in (O_3) is (1.5).
