_Pair of molecules will have similar shape.
Correct answer: D. BF3 and SO3
- A. SO3 and PCl3
- B. Alcl3,Bcl3
- C. CO2 and SO2
- D. BF3 and SO3
Explanation
BF3 has a trigonal planar molecular geometry. The central boron (B) atom forms three sigma bonds with three fluorine (F) atoms. There are no lone pairs on boron, and the bond angles are around 120 degrees. SO3 also has a trigonal planar molecular geometry. The central sulfur (S) atom is bonded to three oxygen (O) atoms. The molecule has no lone pairs, and the bond angles are around 120 degrees.

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.
