On the hybridization of n
N should be sp2 hybridization. One S hybridizes with two P's to form three sp2 hybrid orbitals. Each SP2 hybrid orbital has one electron and a pair of electrons on the remaining P orbitals, and the space structure is a plane triangle. C should be sp3 hybrid, * * * has four orbitals, each with an electron, and the spatial structure is a regular tetrahedron structure, which looks quite similar to the structure in the figure.
