Which of the following involves synergic bonding?

Two important physical evidences supporting the synergic bonding in non-classical complexes are bond lengths and vibrational spectra. Vibrational spectra is based on the fact that the compression and extension of a bond may be analogous to the behaviour of a spring and obeys Hook's law. overline(v)=(1)/(2pic)sqrt((k)/(mu))cm^(-1) where, k=force force constant of the bond which is directly proportional to bonnd strength of CO mu= reduced mass of ligand overline(v) =stretching frequency of the CO bond c=velocity of light Q. In which of the following ligand, sigma -bond order does not change during synergic bonding in their respective complexes:

The pi acceptor ligands are those which possess vacant pi- orbitals in addition to the lone pairs of electrons Which of the following complex ion has the highest C-O bond length ? (a) [V(CO)_(6)]^(o+) (b) Ni(CO)_(4) (c ) Fe(CO)_(5) (d) [Mn(CO)_(6)]^(o+) .
