Question

write the increasing order of bond energy. c-c,N-N,O-O,F-F​

Answer 1

The increasing order of bond energy is given as: O-O < F-F ​< N-N < C-C.

- The main cause of this trend is the strong electronic repulsion between the lone pair of electrons on the atoms.

- More the electrons, more the repulsion and less bond energy.

- Only the bond energy of O-O is less than F-F due to the small size of F atom and strong interaction between its atoms.
