Question:
Describe the change in hybridisation (if any) of the Al atom in the following reaction.

Answer:

Here in the given equation AlCl₃ , Al is shifting its hybridization state from sp² to sp³ because if we see the electronic configuration of Al it is [Ne] 3s² 3p¹, i.e it has 3 electrons in its valence shell during ground state.In its excited state its one s orbital & two p orbitals will take part in hybridization to form sp² hybrid orbital.

The orbital picture of aluminium in the excited state can be represented as:

Now according to the given reaction the product formed AlCl₄- , will only be formed if its 3pz orbital is also filled by one electron in its excited state to form a sp³ hybrid orbital .therefore Al will shift its hybridization form sp² to sp³ to form a tetrahedral shape
