Answer:
The hybridisation of BeCl₂, in solid state and above 1200 K is respectively
(4) sp3, sp
Explanation :
If we look at its structure it is seen that it has Sp hybridization .
This is because : Beryllium only has two electrons and chlorine has 7 electrons and it needs one .Therefore , it shows sp hybridisation .
But in in real,the solid state of BeCl2 involves donation of a pair of electrons from the chlorine to a neighboring BeCl2 molecule at a 45 degree angle and this forms a coordination bonds with the beryllium in each case .
In it each beryllium forms four bonds, which require that it be sp3 hybridized. But if we look at single molecule of BeCl₂ solid-state beryllium chloride sp hybridization.
