Which is not an example of polar covalent bond?
Correct answer: D. C - H
- A. O - Cl
- B. C - Cl
- C. S - O
- D. C - H
Explanation
Notice the word NOT in question If two atoms have an electronegativity difference of 0.4 or less, they form a non- polar covalent bond. If two atoms have an electronegativity difference between 0.4 and 1.7, they form a polar covalent bond. C-H is a non- polar covalent bond. C-H =2.5-2.1 = 0.4

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.
