Question

Which of the following structures is the most preferred and hence of lowest energy for \( \text{SO}_3 \)?

• A. A
• B. B
• C. C
• D. D

Hint:

In molecules like \( \text{SO}_3 \), resonance and electron distribution make certain structures more stable.

Answer 1

The Correct Option is D

The structure with the double bonds between the sulfur and oxygen atoms (i.e., \( \text{O} = \text{S} = \text{O} \)) is the most stable due to the resonance structures and the least repulsion between atoms.

Step 2: Conclusion.
The most preferred structure is option (d), where sulfur is double-bonded to each oxygen.
