Question

Unlike for B2, C2, or N2, orbital mixing is not significant in determining the energies of the molecular orbitals for F2. Why is orbital mixing not significant for F2? 0 A. The energies of the s and p orbitals of fluorine are too far apart for mixing to occur. B. The bonding symmetry of the s orbital of a fluorine does not match any of the p orbitals of the other fluorine. ° C. The s orbital cannot overlap with any of the p orbitals of the other fluorine due to the geometry of the F2 molecule. D. Both A and B. E. Both A and C O F. Both Band C O G. A, B, and C are all reasons that orbital mixing is not significant for F2

Explanation / Answer

The extent of orbital mixing is inversely proportional to their energy separation. The energy gap between the 2s and 2p orbital in the elements becomes larger as the atomic number increases.  It is larger in F than others mentioned here. so orbital mixing is not significant in F2.

option A
