Which pair has species with different shapes?
Correct answer: B. NH3 and BF3
- A. BeCl2 and CO2
- B. NH3 and BF3
- C. SCl2 and H2O
- D. CH4 and NH4+
Explanation
The correct answer is b) NH3 and BF3. These two species have different shapes (trigonal pyramidal and trigonal planar, respectively). The other options have species with the same shapes or molecular geometries.

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.
