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. Synergic bonding is absent in:

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. Synergic bonding is absent in:
Answer» `[Mo(CO)_(6)]` `[CR(CO)_(3)(B_(3)N_(3)H_(6)]` `[Sc(CO)_(6)]^(3+)` `[NI(CN)_(4)]^(4-)` Solution :`overset(+III)(Sc):3d^(@)4S^(@)`, as d-orbitals at `overset(+III)(Sc)` are empty, hence, there is no synergic bonding in `[Sc(CO)_(6)]^(3+)`.
