Which of the following molecules has a linear structure?
Correct answer: D. BeCl₂
- A. H₂S
- B. SO₂
- C. O₃
- D. BeCl₂
Explanation
In Beryllium Chloride (BeCl₂), the central Beryllium atom has two bonding pairs and zero lone pairs of electrons. According to VSEPR theory, this arrangement minimizes repulsion by adopting a linear geometry with a 180° bond angle. The other molecules are bent.

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.
