Correct answer: A. Angular
- A. Angular
- B. Trigonal pyramidal
- C. Tetrahedral
- D. None
Explanation

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.
