The hybridization of the boron atom in BH₃ is sp₂. This is because the molecule has a trigonal planar geometry with 120° bond angles, which is the result of the boron atom mixing one 's' orbital and two 'p' orbitals to form three sp₂ hybrid orbitals.
In BH₃ molecule H-B-H bond angle is 120°. What kind of hybridization is likely?
