How many pure covalent bonds are there in NH+4 ion:
Correct answer: A. 0
- A. 0
- B. 1
- C. 3
- D. 4
Explanation
The NH+4 ion (ammonium ion) has no pure covalent bonds. All the bonds within the NH+4 ion are polar covalent bonds. In the ammonium ion, nitrogen (N) is bonded to four hydrogen (H) atoms. Each of these bonds involves the sharing of electrons between the N and H atoms, but due to the electronegativity difference between nitrogen and hydrogen, the electrons are not shared equally. As a result, the bonds are polar covalent, with nitrogen having a partial negative charge and each hydrogen having a partial positive charge.

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.
