alleryThe shape of an ammonia (NH3) molecule is:
ALinear
BPyramidal
CTrigonal planar
DTetrahedral
Answer & Solution
Correct answer: B. Pyramidal
1. Nitrogen has 3 bond pairs and 1 lone pair.
2. The four electron pairs would lie tetrahedrally.
3. The lone pair pushes the three N-H bonds down a bit.
4. So the visible atomic shape is trigonal pyramidal.
5. Bond angle is about 107 degrees.
