Which of the following has trigonal planar geometry?
Correct answer: C. SO3
- A. SO2
- B. CCl4
- C. SO3
- D. H2O
Explanation
Sulfur trioxide has a trigonal planar molecular geometry. It consists of three oxygen atoms bonded to a central sulfur atom, with no lone pairs on sulfur. This arrangement results in a trigonal planar geometry.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
