1.	Two important physical evidence support the synergic bonding in non-classical complexes-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 spring and obeys Hooke's law. overset(-)v=(1)/(2pic) sqrt((K)/(mu))cm^(-1) Where, K=force constant of the bond which is directly proportional to bond strngth mu="reduced mass of ligand" overset(-)v="stretching frequency of the CO bond" C="velocity of light" In compound [M(CO)N]^(z) the correct match for highest M-C bond length for given M, N and Z respectively
Answer» `{:(M,N,Z),(Ti,6,0):}` `{:(M,N,Z),(Ti,6,-1):}` `{:(M,N,Z),(Ti,6,-2):}` `{:(M,N,Z),(Ti,6,+1):}` Solution :`[Ti(CO)_(6)]^(z)` As charge (+ve)`uarr` on CENTRAL ATOM, synergic bonding `darr` and M-C bond length elongates.
