If the sharing of an electron pair is unequal and the atoms have an electronegativity difference of 1.4 to 1.6, what is this type of sharing called?
Correct answer: B. Polar covalent
- A. Ionic
- B. Polar covalent
- C. Non-polar covalent
- D. Metallic
Explanation
When there is an unequal sharing of electrons due to a moderate difference in electronegativity between the bonded atoms, the bond is classified as polar covalent. This creates partial positive and partial negative charges on the atoms. An electronegativity difference of 1.4-1.6 falls within this range.

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.
