The chemical species having smallest bond angle:
Correct answer: D. NBr3
- A. NH3
- B. NCl3
- C. NF3
- D. NBr3
Explanation
NF3 has a bond angle of approximately 107 degrees, similar to that of ammonia (NH3). The lone pair of electrons on the central nitrogen (N) atom contributes to the smaller bond angle compared to the ideal tetrahedral angle.

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.
