The strongest bond is:
Correct answer: D. C = O
- A. C - O
- B. C = C
- C. C - C
- D. C = O
Explanation
The strongest bond among the given options is the C=O bond, with a bond energy of 799 kJ/mol. This high bond energy indicates a strong double bond between carbon and oxygen, making it the strongest compared to the others. The C-C single bond has the lowest bond energy at 348 kJ/mol, making it the weakest. The C-O single bond, with a bond energy of 358 kJ/mol, is slightly stronger than the C-C bond but still not the strongest. The C=C double bond has a bond energy of 614 kJ/mol, which is stronger than both C-C and C-O but still not as strong as C=O.

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.
