Explain Sp^(2) hybridisation taking boron trichloride (BCl_(3)) as an example.

Answer»

Solution :Boron (5)
Electronic configuration `1-s^(2)2-s^(2) 2p^(1)`

Here one 2s and two 2p half filled orbitals undergo HYBRIDIZATION to GIVE three `sp^(2)` HYBRID orbitals with these hybrid orbitals. The P-orbitals of chlorine MOLECULE overlap to form `pi` bonds.
