Question

A.) A researcher has just reported the existance ofF22+. Would you expect this speies toexist according to the Molecular Orbital Theory? B.)Using the MolecularOrbital Theory, construct an energy level diagram for thecyanide ion. Calculate the bond order. A.) A researcher has just reported the existance ofF22+.

Explanation / Answer

We Know that :    F22+ contains 18 - 2= 16 electrons    The molecular - orbital electronic configurationof F2+2     KK 2s2 *2s2 2px2 [ 2py = 2pz ]4 [ * 2p y1 = * 2 pz1 ]         Bond order = 1 / 2 ( Number of electrons in bondingorbital - Number of electrons in anti-bonding orbital)                              =   1 / 2 ( 8 - 4 )                               = 2           Therfore F2+2 exists .         ForCN- the total number of electrons = 6 + 7 + 1                                                                      = 14         KK 2s2 * 2s 2   [ 2py = 2 pz ] 2   2 px2            Bond order = 1 / 2 ( Number of electrons in bondingorbital - Number of electrons in anti-bonding orbital )                              =   1 / 2 ( 8 - 2 )                               = 3                   Bond order = 1 / 2 ( Number of electrons in bondingorbital - Number of electrons in anti-bonding orbital )                              =   1 / 2 ( 8 - 2 )                               = 3                                     =   1 / 2 ( 8 - 2 )                               = 3
