Question

Place the following molecules in order from smallest to largest H-N-H bond angles: NH₄⁺,NH₃,and NH₂^-. A) NH₄⁺ < NH₃ < NH₂^- B) NH₄⁺ < NH₂^- < NH₃ C) NH₂^- < NH₃ < NH₄⁺ D) NH₂^- < NH₄⁺ < NH₃ E) NH₃ < NH₂^- < NH₄⁺

Quizplus · Accepted Answer

The bond angle decreases with increasing lone pairs. NH4+ has no lone pairs (109.5°), NH3 has one lone pair (107°), and NH2- has two lone pairs (104.5°).
