The percentage of co-ordinate covalent bonds present in BF₄⁻ and NH₄⁺ respectively is:
Correct answer: D. 25% each
- A. 25% and 33%
- B. 33% each
- C. 33% and 25%
- D. 25% each
Explanation
In both the tetrafluoroborate ion (BF₄⁻) and the ammonium ion (NH₄⁺), there are four total covalent bonds. In each case, one of these four bonds is a coordinate covalent bond. Therefore, the percentage of coordinate covalent character is 1 out of 4, or 25% for each ion.

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.
