The shape of an ammonia molecule is:
Correct answer: E. Pyramidal
- A. Angular
- B. Tetrahedral
- C. Linear
- D. Planar
- E. Pyramidal
Explanation
The shape of an ammonia (NH₃) molecule is trigonal pyramidal. This geometry arises because Nitrogen is at the center, bonded to three hydrogen atomst.It has one lone pair of electrons, which repels the bonded pairs, pushing the hydrogen atoms down into a pyramid shape.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
