Which of the following is not correct regarding bond energies – InterviewSolution

1.	Which of the following is not correct regarding bond energies
Answer» The extent of overlap of the atomic orbitals decreases as the size of the atoms INCREASE Among the halogens the bond energy of `F_2` is ABNORMALLY high (159 KJ `mole^(-1)`) The `F_2`, molecule it SELF has a notoriously WEAK bond 159KJ `mol^(-1 )`compared with chlorine 243 KJ `mol^(-1)` According to mulliken in fluorine there are no-d-orbitals in the valence shell and hence `Ppi-dpi` bonding is not possible Answer :B
