Question

The theory that can completely/properly explain. The nature of bonding in (ni(co)4) is

Answer 1

The Nature of bond present in [Ni(Co)₄] is synergistic bond.

• In  (Ni(Co)₄)  the outer most shell configuration is  3d¹⁰4s⁰

• The d orbital is completely filled

• The anti-bonding orbital present in CO is vacant

• Fully filled d orbital gives electron to anti-bonding orbital

• Due to this π-bonding strong bond arises between metal and the carbonyl which is known as synergistic bond
