Which of the following is not tetrahedral ?

A

`SCl_4`

B

`SO_4^(2-)`

C

`Ni(CO)_4`

D

`NiCl_4^2`

Text Solution

Verified by Experts

The correct Answer is:
A

Number of electron pairs around S=5
State of hybridisation `sp^3d`
Lone pair = 1(at equitorial position)
Bond pair =4
Shape of molecule is see-saw
All others are tetrahedral with central atom `sp^3`-hybridised.

Hybridisation is a theoretical concept, as state of hybridisation can not be detected ever the spectroscopically: unlike intermediates or transition state in various reactions but it corrects the predictions which are based on overlapping of pure atomic orbitals. VSEPR theory predicts precisely shape and bond angle in a given molecule. Which of the following is tetrahedral in shape?
