What is sp2 hybridization

Question

Give an example for sp2 hybridization and show it with the help of example

Answer 1

The BF₃ molecule has sp2 hybridization. In this molecule Boron has to form three equivalent bonds, one with each F atom, leading to sp2 hybridization. Boron has three valence electrons, 2 s electrons and 1 p. In this configuration, there is only one unpaired electron in Boron's valence shell. One s electron is promoted up to a p level and then the one s orbital and 2 p orbitals mix to form three equivalent sp2 orbitals, each with one electron that can each take on one electron from a F atom, forming the three necessary bonds. It helps to visualize this by writing out the electron configurations before hybridization and after hybridization.
