To follow the octet rule (eight electrons per atom), each Nitrogen atom needs 3 more electrons i.e. six sp3 orbitals. TABLE 9.4 • Geometric Arrangements Characteristic of Hybrid Orbital Sets. For example, based on the shapes and orientations of the 2s and 2p or-bitals on a carbon atom, it is not obvious why a CH4 molecule should have a tetrahedral geometry. When two p orbitals interact in a side-on way, they form a bonding pi orbital and an antibonding pi orbital. The 2s and all the three (3p) orbitals of carbon hybridize to form four sp3 orbitals. The two sp-hybrid orbitals (each of which consists of Two lobes, one big and one small) lie along a straight line and thus make an angle of 180° with each other.

The directions of these new, hybridized orbitals are the dictators of the spatial arrangement for bonding. VSEPR model assumes that molecular geometry minimizes the repulsion between the valence electrons.
