The F-F bond energy is less than Cl-Cl bond energy because of ______?

The F-F bond energy is less than Cl-Cl bond energy because of ______?

Explanation
  • Fluorine atoms are smaller than chlorine atoms,
  • It leading to greater electron-electron repulsion in the F-F bond.
  • This repulsion weakens the F-F bond.
  • This making its bond energy lower than that of the Cl-Cl bond.
