Explain `sp^(2)` hybridisation in `BF_(3)`.

Explanation

`sp^(2)` hybridisation in boron trifluoride: Boron atom B:
Electronic configuration `[H_(2)]2s^(2)p^(1).`

(ii) In boron, the s orbital and two p orbitals in the valence shell hybridises to generate three equivalent `sp^(2)` orbitals. These 3 orbitals lie in the same y plane and the angle between any two orbitals is equal to `120^(@)`
(iii) The 3 `sp^(2)` hybridised orbitals of boron now overlap with the `2p_(z)` orbitals of fluorine (3 atoms)
This overlap takes place along the axis.
