What is the bond angle in Ammonia?
Correct answer: B. 107.5⁰
- A. 102°
- B. 107.5⁰
- C. 120⁰
- D. 190.5⁰
Explanation
The bond angle in the tetrahedral CH 4 molecule is 109.5°. The replacement of one of the bonded electron pairs with a lone pair compresses the angle slightly. The H-N-H angle is approximately 107°.

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.
