MCQ
What is the geometry of ammonia molecule?
- ATrigonal planar
- BSquare planar
- CLinear
- DPyramidal
✓
Answer
- Pyramidal
Explanation:
The nitrogen atom of ammonia undergoes hybridisation to form 4 sp3 orbitals. Three of these overlap with s orbital of H forming three N-H bonds.
This results in a pyramidal geometry with N atom at the apex and three H atoms at the corners of a triangle base.
