Solution
The correct option is C
Statement 1 is
correct but Statement 2 is not correct.
Statement 1: The structure of SO3 is shown by using more than one structural formula. Statement 2: SO3 is very stable and resonates between these possible structures. These resonance structures are as shown in the above image. Due to resonance, each sulfur oxygen bond in SO3 molecule has partial double bond character. The resonance imparts extra stability to SO3 molecule. Statement 1 is correct but Statement 2 is not correct.
