Which of the following compounds has linear shape:
Correct answer: D. All of them
- A. CO2
- B. CS2
- C. BeCl2
- D. All of them
Explanation
The correct answer is 'All of them'. Each of these molecules-CO2, CS2, and BeCl2-has a linear geometry. CO2 and CS2 have double bonds on opposite sides of the central atom, which results in a linear shape. BeCl2 is linear due to the two chlorine atoms being 180 degrees apart from each other around the central beryllium atom, with no lone pairs on the beryllium. Thus, all options represent linear molecules.

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.
