Which one of the following is covalent in nature?
Correct answer: B. Be3N2
- A. Mg3N2
- B. Be3N2
- C. Ca3N2
- D. Ba3N2
Explanation
Be3N2 is a covalent compound as Be and N have a small difference in electronegativity atoms and are more likely to share electrons rather then transferring them from one to another. All other compounds have a greater difference in electronegativity between the atoms making them polar and ionic.

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.
