Answer
Ozone (O3) and sulfur dioxide (SO2) have resonance structures, while sulfur trioxide (SO3) does not.
Work Step by Step
Let's look at the Lewis structures for the three atmospheric pollutants mentioned: ozone (O3), sulfur dioxide (SO2), and sulfur trioxide (SO3).
1. Ozone (O3):
Lewis structure:
O=O-O
Ozone has a resonance structure where the double bond can shift between the two oxygen atoms:
O-O=O ⇌ O=O-O
2. Sulfur dioxide (SO2):
Lewis structure:
O=S=O
Sulfur dioxide has a resonance structure where the double bond can shift between the two oxygen atoms:
O-S-O ⇌ O=S=O
3. Sulfur trioxide (SO3):
Lewis structure:
O=S=O
O/
\
O
Sulfur trioxide has a trigonal planar structure with three equivalent S-O bonds. It does not have any resonance structures.
