Which option shows all the molecules with bond angle 109.5 degrees:
Correct answer: C. SiCl4 , NH4+ , CH4
- A. CH4 , NH4+ , PH3
- B. SiCl4 , H2O , BeCl2
- C. SiCl4 , NH4+ , CH4
- D. CH4 , CCl4 , NH3
Explanation
Since all molecules stated in option C are tetrahedral in shape, where a central atom is located at the center with four substituents that are located at the corners of a tetrahedron. Hence they all have bond angles that are 109.5 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.
