Ligands are broadly classified into two classes classical and non-classical ligands, depending on their donor annd acceptor ability. Classical ligands form classical complexes while non-classical ligands form non-classical complex. Bonding mechanism in non-classical is called synergic bonding. Q. In compound [M(CO)_(n)]^(x), the correct match for highest 'M-C' bond length for given M, n and z respectively:

1.	Ligands are broadly classified into two classes classical and non-classical ligands, depending on their donor annd acceptor ability. Classical ligands form classical complexes while non-classical ligands form non-classical complex. Bonding mechanism in non-classical is called synergic bonding. Q. In compound [M(CO)_(n)]^(x), the correct match for highest 'M-C' bond length for given M, n and z respectively:
Answer» M-Cr, n-6, z-0 M-V, n-6, z- `-1` M-Ti, n-6, z- `-2` M-Mn, n-6, z- `+1` Solution :Higher the positive oxidation STATE of metal, poor will be `M overset(pi) to l`. HENCE `overset(+1)(Mn) -C` bond will longer AMONG given complexes.
