What is the molecular geometry of NH3 according to VSEPR theory?
Correct Answer: Trigonal pyramidal
- Step 1: Identify the molecule. We are looking at NH3, which is ammonia.
- Step 2: Count the number of atoms bonded to the central atom (Nitrogen). NH3 has three hydrogen atoms bonded to nitrogen.
- Step 3: Count the lone pairs on the central atom (Nitrogen). In NH3, there is one lone pair on nitrogen.
- Step 4: Use VSEPR theory to determine the shape. With three bonding pairs and one lone pair, the shape is trigonal pyramidal.
- Step 5: Conclude that the molecular geometry of NH3 is trigonal pyramidal.
