Question

The structure of ozone most closely resembles 1. , a linear molecule with different lengths of chemical bonds. 2. , a bent molecule with the same length of chemical bonds. 3. , a linear molecule with the same length of chemical bonds. 4. , a bent molecule with different lengths of chemical bonds.

Answer 1

Ozone is a bent molecule with identical O-O bond lengths due to resonance, making the concept of a "half-bond" model more accurate than any single resonance structure.

Step-by-step explanation:

The structure of ozone most closely resembles a bent molecule with the same length of chemical bonds. Ozone, or O3, is a molecule composed of three oxygen atoms, and it has a resonant bonding structure. While it was once thought that ozone exhibited one single bond and one double bond, research has shown that the two O-O bonds are actually identical in length and the overall structure of the molecule is bent. This is due to the phenomenon of resonance, where equivalent Lewis dot structures, also known as resonance structures, depict the bonding in the ozone molecule. These structures indicate that the positions of the atoms remain the same but the positions of the electrons differ. The "half-bond" model of ozone provides a better description of its electronic structure than the idea of alternating single and double bonds.

Answer 2

A bent molecule with the same length of chemical bonds

Step-by-step explanation:

Ozone has three 3 oxygen atoms and its molecular formula of ozone is
`O_3`.

The central oxygen atom is sp2 hybridized and has one lone pair. Because sp2 hybridization and lone pair, shape is bend. Resonance occur in ozone because lone pair and double bond are in conjugation, therefore, ozone can be represented as a resonance hybrid with same bond lengths.

Therefore, option 2 is correct.

A bent molecule with the same length of chemical bonds
