    Compound 1: Sodium borohydride

    In sodium borohydride (NaBH4), B is a central metal.

    Electronic configuration of B is 1s2 2s2 2p1.

    B undergoes sp3 hybridization in NaBH4, to generate 4 hybrid orbitals. These hybrid orbitals, forms sigma bond with 4 'H' atoms. Due to this, the structure of sodium borohydride in tetrahedral.

    Compound 2: B oron trifluoride

    In boron trifluoride (BF3), B is a central metal.

    Electronic configuration of B is 1s2 2s2 2p1.

    B undergoes sp2 hybridization in NaBH4, to generate 3 hybrid orbitals. These hybrid orbitals, forms sigma bond with 3 'H' atoms. Due to this, the structure of boron trifluoride is triangular planner.
