MCQ
What is the geometry of ammonia molecule?
- ATrigonal planar
- BSquare planar
- CLinear
- ✓Pyramidal
✓
Answer
Correct option: D.
Pyramidal
The nitrogen atom of ammonia undergoes hybridisation to form $4\ sp^3$ 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.
This results in a pyramidal geometry with $N$ atom at the apex and three $H$ atoms at the corners of a triangle base.
