With the help of VBT explain the hybridisation in tetracarbonyl nickel and sketch the shape of the complex.

Both [Ni(CO)_4] and [Ni(CN)_4]^(2-) , are diamagnetic. The hybridizations of nickel in these respectively, are

Statement-1:Nickel is purified by the thermal decomposition of nickel tetracaerbonyl. Statement-2: Nickel is a transition element.
