Which of the following has bond angles slightly less than 120^$\circ$? A) NO₃^- B) HO₂^- C) NO₂^- D) CS₃²^- E) I₃⁺

Question

Quizplus · Accepted Answer

NO₂F1F1F1S1^- has a trigonal planar molecular geometry with bond angles of exactly 120 degrees. However, nitrogen is replaced by oxygen in option C which results in partial double-bond character and bond angles slightly less than 120 degrees. The other options either have bond angles of exactly 120 degrees or have different molecular geometries.
