Q1. While studying molecular geometry, a student notices that the H-N-H bond angle in ammonia is 107.5 degrees instead of 109.5 degrees. This distortion occurs because:
Answer: Lone pair-bond pair repulsion
Explanation: Ammonia's bond angle is 107.5 due to lone pair-bond pair repulsion. 109.5 is tempting as the ideal tetrahedral angle for sp3.
