Practice question · Multiple choice
Bonding models treat ionic and covalent interactions as discrete categories, yet physical bonds occupy a continuum. What does this distinction imply for a molecule like hydrogen fluoride (ΔEN = 1.9)?
Hints
- Does a large dipole moment automatically prevent atoms from sharing electrons?
- How do macroscopic structures differ from individual molecular units?
Show the answer
A. It displays molecular behaviour despite a high polarity
Why
Categorising bonds by arbitrary numerical thresholds overlooks their hybrid nature. High difference in electronegativity creates substantial polarity without necessarily stripping a substance of its molecular identity or enforcing a lattice.
