WebJul 28, 2016 · 1 Answer anor277 Jul 28, 2016 Up to 4. Explanation: Typically, boron forms 3 covalent bonds. Boron can form a fourth covalent bond and thus acquire a formal negative charge. Sodium borohydride, and tetra-alkylborates, −BR4, are examples. Answer link WebIn sp hybridization, one s orbital and one p orbital hybridize to form two sp orbitals, each consisting of 50% s character and 50% p character. This type of hybridization is required whenever an atom is surrounded by two groups of electrons. Created by Jay.
