In CCl4, all C-Cl bonds are _ but the molecule is _ overall.
Correct answer: A. Polar, non-polar.
- A. Polar, non-polar.
- B. Non-polar, neutral.
- C. Polar, Neutral.
- D. Neutral, non-polar
Explanation
CCl4 is non-polar in nature. Although the four bonds (C-Cl) are polar because of the difference in electronegativity of Chlorine (3.16) and Carbon(2.55), CCl4 is non-polar because the bond polarity gets canceled out with each other due to the symmetrical geometrical structure (tetrahedral) of the CCl4 molecule.

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.
