The table shown below gives the bond dissociation energies of single covalent bonds of carbon atoms with elements A, B, C, and D. Which of the following has the smallest atom?

Correct answer: D. D

  • A. A
  • B. B
  • C. C
  • D. D

Explanation

The smaller the atom the closer the orbital electrons are to the nucleus, making the forces and thus the bond energy highest. The answer to this question is hence C-D.

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.
