What will be the geometrical shape of a molecule that contains two lone pairs and two bond pairs of electron in valence shell of central atom?
Correct answer: C. Angular
- A. Tetrahedral
- B. Trigonal pyramidal
- C. Angular
- D. Linear
Explanation
If there are two bond pairs and two lone pairs of electrons the molecular geometry is angular or bent (e.g. H2O).

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.
