It is also possible to have 5 electron pairs (sp3d hybridization) and 6 pairs of electrons (sp3d2 hybridization.) On the periodic table, Boron's in group 3. In the ground state boron (B) could form only one bond because it has only one unpaired B. BH3 would orient in an electric field. C. BH3 is a polar . However, the molecular species BH 3 is a very strong Lewis acid. It is bonding in a non-horizontal direction to at least one hydrogen. 1. HYBRIDIZATION IN BH3 Boron in "BH"_3 has to contribute three sp^2-hybridized atomic orbitals to bond because: It is bonding to more than one hydrogen. The B−H and N−H distances are 1.15 and 0.96 Å, respectively. The mixture of s, p and d orbital forms trigonal bipyramidal symmetry. Three of these electrons are sp2−hybridized, and they form 2×C−H, and 1×C−O, bonds. Trihydridoboron, also known as borane or borine, is an unstable and highly reactive molecule with the chemical formula BH 3.The preparation of borane carbonyl, BH 3 (CO), played an important role in exploring the chemistry of boranes, as it indicated the likely existence of the borane molecule. Boron goes in the center, Hydrogens on the outside. As a result the hybridization of NH3 molecule is sp3 and bond angle from central atom is 107°. NH3 Hybridization – SP3.
