The bond formed between NH3 and BF3 is a coordinate bond, because NH3 is a _ due to the presence of one lone pair.
Correct answer: B. Donor
- A. Acceptor
- B. Donor
- C. Neutral
- D. Negatively charged
Explanation
Option B is correct as a coordinate covalent bond is formed between a molecule with that donates a lone pair and a molecule that accepts the lone pair. The bond is formed, and they share the lone pair of electrons. So the molecule with the lone pair is the "donor" (NH3) and the molecule accepting it is the acceptor (BF3).

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.
