Sulfur trioxide (SO3) has a Lewis structure where the sulfur atom is at the center with three oxygen atoms bonded to it. It includes one double bond with each oxygen, ensuring all atoms satisfy the octet rule. This results in a sulfur atom with no lone pairs and a highly symmetrical trigonal planar shape.

FAQs & Answers

  1. What is the shape of the SO3 molecule? The SO3 molecule has a trigonal planar shape, with sulfur at the center bonded to three oxygen atoms symmetrically.
  2. How many bonds are in the Lewis structure of SO3? In the Lewis structure of SO3, the sulfur atom forms three double bonds with three oxygen atoms.
  3. Does sulfur have lone pairs in SO3 Lewis structure? No, in the SO3 Lewis structure, the sulfur atom does not have any lone pairs.
  4. How does SO3 satisfy the octet rule in its Lewis structure? Each oxygen atom has a complete octet with bonding and lone pairs, and sulfur forms double bonds to fulfill its octet, resulting in a stable configuration.
