What is the bond angle of NH3?
Understand the Problem
The question is asking for the bond angle in ammonia (NH3), which is the angle formed between the hydrogens attached to the nitrogen atom in the molecule. This involves understanding the molecular geometry of ammonia, which is trigonal pyramidal due to the presence of a lone pair on the nitrogen.
Answer
107 degrees
The bond angle of NH3 is 107 degrees.
Answer for screen readers
The bond angle of NH3 is 107 degrees.
More Information
The bond angle in NH3 is 107 degrees due to the lone pair of electrons on nitrogen, which causes greater repulsion than bonding pairs, thus reducing the bond angle from the ideal tetrahedral angle of 109.5 degrees.
Tips
A common mistake is to assume the bond angle is 109.5 degrees due to sp3 hybridization, but you must account for lone pair repulsion.
