According to lewis-dot structure which of the following statement is/are CORRECT about $SO_{3}$ molecule.

Answer:

A, C, D

Solution:

SO₃ has resonance structures with S–O bonds. Two of these bonds are coordinate (dative) bonds where sulfur donates lone pairs to oxygen.

Lone pair to bond pair ratio is 2 (due to resonance and bonding arrangement).

Number of sigma bonds = 3 (one σ bond per S–O bond).

SO₃ is not strictly hypervalent because the bonding electrons are delocalized (resonance stabilizes it).
