Why do NH₃ and SCl₂, despite having comparable bond angles, have different molecular geometries?

• A. NH₃ and SCl₂ have different molecular geometries because they have different electron arrangements.
• B. NH₃ and SCl₂ have different molecular geometries because they have different numbers of lone pairs.
• C. NH₃ and SCl₂ have different molecular geometries because they have different numbers of electron groups.
• D. All of the above.

Answer: (B)
